At the present time, restrictive laws are in force in the United
|
|
States and it is very difficult for researchers to abide by the
|
|
regulations which govern efforts to obtain legal approval to do work
|
|
with these compounds in human beings.... No one who is lacking legal
|
|
authorization should attempt the synthesis of any of the compounds
|
|
described in these files, with the intent to give them to man. To do
|
|
so is to risk legal action which might lead to the tragic ruination of
|
|
a life. It should also be noted that any person anywhere who
|
|
experiments on himself, or on another human being, with any of the
|
|
drugs described herin, without being familiar with that drug's action
|
|
and aware of the physical and/or mental disturbance or harm it might
|
|
cause, is acting irresponsibly and immorally, whether or not he is
|
|
doing so within the bounds of the law.

#60 DMPEA; 3,4-DIMETHOXYPHENETHYLAMINE
|
|
|
|
SYNTHESIS: A solution of 33 g 3,4-dimethoxybenzaldehyde in 140 mL
|
|
acetic acid was treated with 23 mL nitromethane and 12.5 g anhydrous
|
|
ammonium acetate, and heated on the steam bath for 45 min. To this
|
|
there was slowly added, with good stirring, 300 mL H2O, and the
|
|
resulting solids were removed by filtration. The product was finely
|
|
ground under a small amount of MeOH, filtered again, and air dried to
|
|
give 13.5 g 3,4-dimethoxy-'-nitrostyrene with a mp of 142-143 !C.
|
|
|
|
To a stirred suspension of 12.0 g LAH in 500 mL anhydrous Et2O that
|
|
was at a gentle reflux and under an inert atmosphere, there was added
|
|
11.45 g 3,4-dimethoxy-'-nitrostyrene by leaching it from a thimble in
|
|
a modified Soxhlet condenser. The addition took 2 h and the refluxing
|
|
was maintained for another 16 h. After cool-ing to room temperature,
|
|
the excess hydride was destroyed by the cautious addition of 500 mL
|
|
1.5 N H2SO4. The phases were separated, and to the aqueous phase
|
|
there was added 250 g potassium sodium tartrate. The pH was brought
|
|
to >9, and the clear solution was extracted with 3x100 mL CH2Cl2.
|
|
Remo-val of the solvent from the combined extracts under vacuum gave
|
|
5.2 g of a pale yellow oil. This was dissolved in 300 mL anhydrous
|
|
Et2O and saturated with anhydrous HCl gas, giving 5.0 g of a slightly
|
|
sticky off-white solid. This was recrystallized from 75 mL of boiling
|
|
CH3CN to give 3.3 g 3,4-dimethoxyphenethylamine hydrochloride (DMPEA)
|
|
as beautiful white crystals.
|
|
|
|
DOSAGE: greater than 1000 mg.
|
|
|
|
DURATION: unknown.
|
|
|
|
QUALITATIVE COMMENTS: (with 500 mg) Nothing.
|
|
|
|
(with 1000 mg) Nothing.
|
|
|
|
(with 10 mg i.v.) RNothing.
|
|
|
|
(with 1000 mg of 3,4-dimethoxyphenylacetic acid, a major human
|
|
metabolite of DMPEA) RNothing.
|
|
|
|
(with 500 mg of N-acetyl-3,4-dimethoxyphenethylamine, a major human
|
|
metabolite of DMPEA) RNothing.
|
|
|
|
EXTENSIONS AND COMMENTARY: Why all the interest? Why keep pursuing a
|
|
compound that is so obviously without activity? Or a metabolite that
|
|
is also without activity? The answer is that these are totally
|
|
fascinating compounds just because they have no activity! By the way,
|
|
in this instance, I actually made up most of the quotations. I am not
|
|
sure that the subjects actually said, RNothing,S but they did report
|
|
that there were no effects. In my own experiments, my notes record
|
|
the phrase, RNo effects whatsoever.
|
|
|
|
A little background: one of the transmitter heavyweights in the brain
|
|
is dopamine. Dopamine is called dopamine because it is an amine that
|
|
comes from an amino acid that is 3,4-dihydroxyphenylalanine and this,
|
|
in German, is Di-Oxo-Phenyl-Alanine, or DOPA. The levo-optical (or
|
|
L-) isomer of DOPA has rather cutely been called the punch-drunk
|
|
Spanish matador, or El Dopa. But that is not part of the story.
|
|
|
|
The story is really about the RPink Spot of Schizophrenia.S Many years
|
|
ago, an observation was made in a biochemical laboratory on the East
|
|
Coast that stirred up a rolling controversy. It had been found that
|
|
if the urines of schizophrenic patients (sloppily called
|
|
Rschizophrenic urinesS) were extracted in such and such a way, and the
|
|
extracts chromatographed, a pink spot would develop at a particular
|
|
place on the chromatogram. Well, if this proved to be true with
|
|
urines of a sick population, and were this proved to be different from
|
|
the urines of a healthy population, it would constitute an objective
|
|
diagnosis of schizophrenia. A simple chemical test to confirm a
|
|
pathology that had defied all efforts to achieve consensus amongst the
|
|
psychiatrists of the world.
|
|
|
|
The literature was suddenly filled with dozens of papers. Researcher
|
|
A confirmed that the pink spot was found with schizophrenics, and not
|
|
with normal controls. Researcher B found the pink spot in all urines,
|
|
regardless of pathology. Researcher C found it in no urines at all.
|
|
Researcher D argued that it was a factor from the hospital diet.
|
|
Researcher E found that the pink spot reflected the time of day that
|
|
the urine sample was collected. Researcher F drew a conclusion about
|
|
where truth might lie by tallying the number of papers that supported
|
|
argument A, B, C, D, or E.
|
|
|
|
The only confirmable fact that endured was that the pink spot was due
|
|
to DMPEA. So a bright spotlight was directed towards its possible
|
|
role in mental illness. And this expressed itself in the simple
|
|
question: would it produce schizophrenia in a normal subject? No.
|
|
And in a way I am comforted that that did not evolve into a simple
|
|
litmus test for a schizophrenic diagnosis. There are so many
|
|
cultural, political, and social factors that come to bear on the
|
|
assignment of a diagnosis of mental illness, that I would have been
|
|
forever skeptical of a neat biochemical marker.
|
|
|
|
A chemical modification of DMPEA that has been explored in this
|
|
question of pink spots, mental pathology, and diagnostic markers, is
|
|
the corresponding acetamide. One of the metabolites of DMPEA was
|
|
found to be the N-acetyl deriva-tive, N-acetyl-3,4-
|
|
dimethoxyphenethylamine. It was found to be demethylated in man, and
|
|
to have pharmacological activity in animals. Maybe this was the
|
|
active compound that could be involved in the schizophrenic process.
|
|
But human trials with it, as with the principal metabolite
|
|
3,4-dimethoxyphenylacetic acid, showed nothing at all in man.
|
|
|
|
Another chemical modification is the beta-hydroxy analogue of DMPEA.
|
|
It has been explored separately, and is the subject of its own recipe,
|
|
in its own rights. See DME.
|
|
|
|
Pink was not the only colorful spot associated with schizophrenia.
|
|
Somewhere at about this same time, a research paper from Canada
|
|
reported the observation of a mauve spot in the chromatographic
|
|
analysis of urines of schizophrenic patients. This had nothing to do
|
|
with DMPEA. I was working closely with a researcher at the
|
|
psychiatric institute and we were fascinated by, again, a possible
|
|
diagnostic marker. We assayed the urines of the next 10 patients
|
|
being admitted as acute schizophrenics. No trace of mauve. We wrote
|
|
to Canada, and verified the analytical procedure. We were told that
|
|
the whatzis should have been added after, rather than before, the
|
|
whosey, and that we should have heated for 30, not 10 minutes. Okay.
|
|
We assayed the urines of the next 10 patients being admitted using
|
|
these new directions. No trace of mauve. Another call to Canada, and
|
|
we were informed that we still werenUt doing it right. They were
|
|
consistently batting a 100% positive correlation between mauve spots
|
|
and schizophrenics, and 0% with healthy controls. In fact, they
|
|
actually gave this positive test the name of a disease, Malvaria.
|
|
|
|
Then, that little burst of insight! Aha! What if, just what if, they
|
|
had been seeing something given to their schizophrenics?
|
|
Chlorpromazine was the popular treatment of the day. We took a
|
|
whopping dose of chlorpromazine, and over the next couple of days did
|
|
manage (barely) to collect our urine samples. Both of us were
|
|
positive Malvarians! And three days later, we were again negative.
|
|
We were most likely seeing a metabolite of chlorpromazine. One last
|
|
call to Canada with the ultimate question Q had you given any
|
|
medication to your schizophrenics before your urine analysis? Of
|
|
course (came the answer) Q it would not be ethical to leave them
|
|
untreated. Another color down the drain, and still no objective
|
|
measure for mental illness.
|
|
|
|
By the way, I cannot say I like the chlorpromazine trip. There is no
|
|
real communication either with others or with yourself, with that
|
|
stuff. You are a zombie, but if you are both schizophrenic and a
|
|
zombie, you cannot possibly be troublesome for anybody in the
|
|
emergency room.

#61 DOAM; 2,5-DIMETHOXY-4-(n)-AMYLAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 110 g p-dimethoxybenzene and 102 g valeric
|
|
acid in 168 g polyphosphoric acid was heated on the steam bath for 3
|
|
h, giving a deep red homogeneous solution. This was poured into 1 L
|
|
H2O with good stirring. The strongly acidic, cloudy suspension was
|
|
extracted with 3x200 mL CH2Cl2, the extracts pooled, washed with 4x150
|
|
mL 5% NaOH, and finally once with dilute HCl. The solvent was removed
|
|
under vacuum, and the residual amber oil cooled overnight at 0 !C.
|
|
Some 30 g of crystalline, unreacted dimethoxybenzene were removed by
|
|
filtration, and the 85 g of residual oil distilled at the water pump.
|
|
Another 15 g of di-methoxybenzene came over as an early cut, but the
|
|
fraction boil-ing at 184-192 !C (mostly 188-192 !C) weighed 53.0 g and
|
|
was reasonably pure 2,5-dimethoxyamylophenone. The reaction of the
|
|
acid chloride of valeric acid with p-dimethoxybenzene and anhydrous
|
|
AlCl3 in CH2Cl2 (parallel to the preparation of the butyrophenone
|
|
analog, see DOBU) gave an inferior yield (23.2 g from 92 g
|
|
dimethoxybenzene), but did provide a sizeable sample (12.2 g) of
|
|
2-hydroxy-5-methoxyamylophenone from the basic washes of the crude
|
|
reaction mixture. This pale yellow solid, after recrystallization
|
|
from MeOH, had a mp of 62-62.5 !C. Anal. (C12H16O3) C,H.
|
|
|
|
To 360 g mossy zinc there was added a solution of 7.2 g mercuric
|
|
chloride in 200 mL warm H2O, and this was swirled periodically for 2
|
|
h. The H2O was drained off, and the amalgamated zinc added to a 2 L
|
|
three-neck round-bottomed flask, treated with 200 mL concentrated HCl,
|
|
and heated with an electric mantle. A solution of 53.0 g of
|
|
2,5-dimethoxyamylophenone in 107 mL EtOH containing 30 mL concentrated
|
|
HCl was added drop-wise over the course of 4 h accompanied by 330 mL
|
|
of concentrated HCl added batchwise over this same period. The
|
|
mixture was held at reflux overnight and, after cooling, diluted with
|
|
sufficient H2O to allowed CH2Cl2 to be the lower phase. The phases
|
|
were separated, and the aqueous phase was extracted with 2x200 mL
|
|
additional CH2Cl2. These organic phases were combined, washed first
|
|
with 5% NaOH and then with H2O, and the solvent removed under vacuum.
|
|
Distillation at the water pump yielded two fractions. The first
|
|
distilled from about 100-130 !C, weighed 8.8 g, had a faint smell of
|
|
apples and fennel, and was free of a carbonyl group in the infra-red.
|
|
It proved to be only 50% pure by GC, however, and was discarded. The
|
|
major fraction was a pale amber oil distilling between 152-170 !C and
|
|
was substantially free of smell. It weighed 18.9 g, and was (by GC)
|
|
90% pure 2,5-dimethoxy-(n)-amylbenzene.
|
|
|
|
A mixture of 36.3 g POCl3 and 40.9 g N-methylformanilide was allowed
|
|
to incubate for 0.5 h. To this there was then added 18.5 g of
|
|
2,5-dimethoxy-(n)-amylbenzene and the mixture heated on the steam bath
|
|
for 2 h. This mixture was poured into a large quantity of H2O and
|
|
stirred overnight. The black oily product was extracted with 3x100 mL
|
|
CH2Cl2, and the extracts combined and stripped of solvent under
|
|
vacuum. The black residue was distilled at 180-205 !C at 20 mm/Hg to
|
|
give 12.5 g of a pale amber oil that slowly set up to a crystalline
|
|
mass. An analytical sample was recrystallized from MeOH to provide
|
|
2,5-dimethoxy-4-(n)-amylbenzaldehyde with a mp of 25-26 !C. Anal.
|
|
(C14H20O3) H; C: calcd, 71.16: found, 71.92, 71.74.
|
|
|
|
A solution of 12.3 g 2,5-dimethoxy-4-(n)-amylbenzaldehyde in 50 mL
|
|
acetic acid was treated with 4.0 g anhydrous ammonium acetate and 12
|
|
mL nitroethane. This mixture was heated on the steam bath for 4 h,
|
|
then poured into a large quantity of H2O. This was extracted with
|
|
3x200 mL CH2Cl2, the extracts washed with H2O, and the solvent removed
|
|
to give a deep red oil that, on standing in the refrigerator, slowly
|
|
set to a crystalline mass weighing 13.5 g. An analytical sample was
|
|
recrystallized from MeOH to provide
|
|
1-(2,5-dimethoxy-4-(n)-amylphenyl)-2-nitropropene as fine yellow
|
|
microcrystals with a mp of 44 !C sharp. Anal. (C16H23NO4) C,H,N.
|
|
|
|
To a gently refluxing suspension of 10 g LAH in 500 mL anhydrous Et2O
|
|
under a He atmosphere, there was added by 13.2 g
|
|
1-(2,5-dimethoxy-4-(n)-butyl-phenyl)-2-nitropropene by allowing the
|
|
condensing ether drip into a Soxhlet thimble containing the
|
|
nitrostyrene which effectively added a warm saturated solution of it
|
|
dropwise to the reaction mixture. Refluxing was maintained for 18 h,
|
|
and the cooled reaction flask stirred for several additional days.
|
|
The excess hydride was destroyed by the cautious addition of 1 L 8%
|
|
H2SO4. When the aqueous and Et2O layers were finally clear, they were
|
|
separated, and the aqueous layer was washed with an additional 2x100
|
|
mL Et2O. Removal of the solvent from the organic phase and washings
|
|
provided 4.7 g of a thick red oil that was discarded. The aqueous
|
|
phase was then extracted with 2x200 mL CH2Cl2 which actually removed
|
|
the product as the sulfate salt. This organic phase was washed with
|
|
2x100 mL 5% K2CO3 (removing the H2SO4) and with the evaporation of the
|
|
solvent there was obtained 6.2 g of an oily amber residue. This was
|
|
dissolved in 200 mL Et2O and saturated with anhydrous HCl gas. Fine
|
|
white crystals of 2,5-dimethoxy-4-(n)-amylamphetamine hydrochloride
|
|
(DOAM) separated, were removed by filtration, Et2O-washed and air
|
|
dried, and weighed 5.2 g. The mp of 136-139 !C was increased to
|
|
145-146 !C by recrystallization from CH3CN. Anal. (C16H28ClNO2) C,H,N.
|
|
|
|
DOSAGE: greater than 10 mg.
|
|
|
|
DURATION: unknown.
|
|
|
|
QUALITATIVE COMMENTS: (with 10 mg) There was a clear threshold that
|
|
in no way interfered with my day's activities. I was quite gay and
|
|
voluble at lunch and bubbled on into the afternoon with puns and high
|
|
spirits. There may have been a little motor incoordination as noted
|
|
in handwriting, and there was a strange tenseness during driving.
|
|
There were no sequelae, there was no trouble sleeping, and with this
|
|
potency way down from the lower homologues, I have no pressing desire
|
|
to take this compound to a higher dose.
|
|
|
|
EXTENSIONS AND COMMENTARY: The actual procedure that was published for
|
|
the isolation of this final amine was a different one, one that would
|
|
certainly work, but which was based on the procedures tried and proven
|
|
with the lower homologues. The process described above is just a bit
|
|
bizarre (a sulfate salt extracting into methylene chloride) but it was
|
|
the actual thing that was done. The work was started towards two
|
|
additional compounds but these never got past the first Rketone and
|
|
phenolS stage. p-Dimethoxybenzene was brought into reaction with
|
|
n-caproic acid with polyphosphoric acid (aiming towards
|
|
2,5-dimethoxy-4-(n)-hexylamphetamine, DOHE) but this was dropped when
|
|
DOAM proved to be down in potency. And the reaction between
|
|
p-dimethoxybenzene and benzoyl chloride with anh. aluminum chloride
|
|
went well (aiming towards 2,5-dimethoxy-4-benzylamphetamine, DOBZ). A
|
|
goodly amount of the phenol (2-hydroxy-5-methoxybenzophenone) was
|
|
obtained as fine yellow crystals, but this line of inquiry was also
|
|
dropped.
|
|
|
|
The preparation of DOAM was, as a matter of fact, the last of the
|
|
homol-ogous series of compounds actually completed, which stemmed from
|
|
the original discovery of DOM. The RTen Classic LadiesS concept was
|
|
mentioned under ARIADNE, and the adding of a methyl group in the place
|
|
of a hydrogen atom at the 4-position-methyl led to the synthesis of
|
|
Ms. HECATE and gave rise to DOET. The whole series of
|
|
methyl-ethyl-propyl-butyl-amyl compounds was appealing to me, in that
|
|
the potency seemed to increase initially as the chain got longer, and
|
|
then it abruptly dropped off. WouldnUt it be nice, I thought, if I
|
|
could interest some pharmacologist in looking at this tight set of
|
|
drugs with some animal model, to see if there is some neurotransmitter
|
|
activity that would show a parallel action.
|
|
|
|
I learned of a curious young researcher in Washington who had an
|
|
elegant procedure for measuring serotonin agonist action using the
|
|
(otherwise) discarded sheep umbilical artery strips. These become
|
|
available each year at lambing time, do not cost the life of anything,
|
|
and require very little compound. He assayed my compounds and, lo and
|
|
behold, the serotonin activity also went through a maximum in the
|
|
middle of this series. We published a short paper to this effect,
|
|
which served as a excellent vehicle to get the cogent human data into
|
|
the scientific literature.
|
|
|
|
I have never understood the reasons that there might be connection
|
|
between the twitching of a umbilical artery in a sheep and the
|
|
appearance of an insight in the mind of man. And, I have never
|
|
personally met this pharmacologist. Some day, I hope to do both.

#62 DOB; 2,5-DIMETHOXY-4-BROMOAMPHETAMINE
|
|
|
|
SYNTHESIS: To a well-stirred solution of 1.95 g of the free base of
|
|
2,5-dimethoxyamphetamine (2,5-DMA) in 12 mL glacial acetic acid, there
|
|
was added 1.8 g elemental bromine dissolved in 4 mL acetic acid over
|
|
the course of 5 min. The slightly exothermic reaction was allowed to
|
|
stir for 3 h, and then added to about 200 mL H2O. The cloudy solution
|
|
was washed with 2x100 Et2O, made basic with aqueous NaOH, and
|
|
extracted with 3x100 mL CH2Cl2. Evaporation of the solvent from the
|
|
pooled extracts gave about 3 mL of a pale amber oil which was
|
|
dissolved in 250 mL anhydrous Et2O and saturated with anhydrous HCl
|
|
gas. The fine white crystals of 2,5-dimethoxy-4-bromoamphetamine
|
|
hydrochloride, DOB, were removed by filtration, Et2O washed, and air
|
|
dried. These weighed 1.7 g and had a mp of 195-196 !C.
|
|
Recrystallization from IPA brought this up to 207-208 !C. Proton NMR
|
|
spectroscopy of the hydrochloride salt in D2O gave confidence that the
|
|
bromine atom had uniquely entered the 4-position, in that there were
|
|
only two unsplit aromatic hydrogen atoms present, at 6.97 and at 7.20
|
|
ppm downfield from external TMS.
|
|
|
|
DOSAGE: 1.0 - 3.0 mg.
|
|
|
|
DURATION: 18 - 30 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 0.4 mg) There was a distinct enhancement
|
|
of visual perception, and some strengthening of colors. A clean, cold
|
|
feeling of wind on the skin. I felt an enriched emotional affect, a
|
|
comfortable and good feeling, and easy sleeping with colorful and
|
|
important dreams.
|
|
|
|
(with 2.0 mg) There was a continuous tremor at the physical level,
|
|
and an incredible Moebius strip representation of reality at the
|
|
intellectual level. I was able to enter into personal problems
|
|
easily, and get out again when I chose to. During the next day, there
|
|
were brief lapses of attention, or little fugue states, and it was not
|
|
until the following evening that I was completely myself again.
|
|
|
|
(with 2.8 mg) About three hours into this I had a severe cramp, and
|
|
had a near fainting response to the pain, and yet there was no pain!
|
|
I felt that I was very near a loss of consciousness, and this was most
|
|
disturbing. There were flashes of depersonalization. I saw rings
|
|
around the moon with prismatic colors, and there were long-lasting
|
|
Rafter-imagesS following any viewings of points of light. I was still
|
|
a good plus 1 at 14 hours, but did manage to sleep. It was the next
|
|
day before I was again at baseline.
|
|
|
|
(with 3.0 mg) This was a complex, but a very good day. It involved
|
|
making a large pot of chicken-vegetable soup, and listening to H.L.,
|
|
my favorite Saturday morning fundamentalist Christian radio preacher,

|
bless Tim. The Democrats are not exactly all anti-American dupes of
|
|
Moscow (or the Devil), but to H.L., they are practically, almost,
|
|
next-door to it. The Rapture is supposed to happen tomorrow according
|
|
to a certain book, newly published (just in time, looks like) and he
|
|
is busy softening the possible disappointment of those who may find
|
|
themselves unchanged Monday morning. Wunnerful. It's been one heck
|
|
of a good experiment, and I canUt understand why we waited nine years
|
|
to try this gorgeous stuff. Without going into the cosmic and
|
|
delicious details, let's just say itUs a great material and a good
|
|
level.
|
|
|
|
(with 0.5 mg of the RRS isomer) I am underway, and this is a smooth
|
|
intoxication. I am completely functional, but still really a plus
|
|
two. I would not choose to drive a car. Not very far. I felt a
|
|
rather quick dropping to a plus-one at the fifth hour, but there is a
|
|
residual stimulation still the following morning.
|
|
|
|
(with 1.0 mg of the RRS isomer) By the fourth hour I am absolutely a
|
|
+++ and am searching the kitchen for food. But what I eat is only
|
|
so-so. There is not the introspection or intensity of 2.0 milligrams
|
|
of the racemate material, but this is a rewarding place nonethless.
|
|
At the 18th hour, there was some fitful sleep, with bizarre dreams.
|
|
The next day I was still hungry for altered spaces, and successfully
|
|
challenged the residual plus one with LSD and, as is usually the case,
|
|
acid cut right through the detritus and allowed a direct shot up to a
|
|
+++ again.
|
|
|
|
(with 1.5 mg of the RRS isomer) This is a +++ but it is vaguely
|
|
irrational. I feel a heavy body load, but then the temperature
|
|
outside is over a hundred degrees and I may not be in the best of all
|
|
physical environments. I would not wish any higher dosage. There
|
|
were cat-naps at the twelth hour, but most symptoms were still there
|
|
at the 18th hour. A good experience. It would be interesting to
|
|
compare this, some day, with 3.0 milligrams of the racemate.
|
|
|
|
(with 0.5 mg of the RSS isomer) There are no effects at all.
|
|
|
|
(with 1.0 mg of the RSS isomer) There is something warm and nice at a
|
|
couple of hours into this, but I am no more than threshold, and the
|
|
effects are very slight. By the fifth hour there are no longer any
|
|
effects.
|
|
|
|
EXTENSIONS AND COMMENTARY: The stars had clearly lined up in favor of
|
|
making DOB and exploring its biological activity. This preparation
|
|
had been completed in 1967 and the report of this compound and its
|
|
unprecedently high potency published in 1971. And very shortly, two
|
|
additional papers appeared completely independently. One described
|
|
DOB made via a different route, and describing high activity in rats.
|
|
The other described DOB and a couple of closely related brominated
|
|
amphetamines and their action in man.
|
|
|
|
This is one of the last of the experimental compounds within the
|
|
phenethylamine family on which any animal toxicity studies were
|
|
performed by me prior to human studies. A mouse injected with 50
|
|
mg/Kg (ip) showed considerable twitching and was irritable. Another,
|
|
at 100 mg/Kg (ip), had overt shaking at 20 minutes, which evolved into
|
|
persistent hyperactivity that lasted several hours. Yet another, at
|
|
125 mg/Kg (ip), lost much of her righting reflex within 15 minutes,
|
|
entered into convulsions at 50 minutes, and was dead a half hour
|
|
later. A fourth mouse, at 150 mg/Kg (ip), entered into spontaneous
|
|
convulsions within 10 minutes, and expired in what looked like an
|
|
uncomfortable death at 22 minutes following injection. What was
|
|
learned? That the LD/50 was somewhere between 100 and 125 mg/Kg for
|
|
the mouse. And an effective dose in man of maybe 2 mg (for an 80 Kg
|
|
man) is equivalent to 25 ug/Kg. Therefore the index of safety (the
|
|
therapeutic index, the lethal dose divided by the effective dose) is
|
|
well over a thousand. I feel that two mice were killed without
|
|
anything of value having been received in return.
|
|
|
|
Actually, it is very likely that the damaging, if not lethal, level of
|
|
DOB in man is a lot lower than this ratio would imply. There was a
|
|
report of a death of a young lady following the snorting of an amount
|
|
of DOB so massive, there was the actual recovery of over nine
|
|
milligrams of the drug from her body tissues in the post-mortem
|
|
examination. It was said that she and her companion had thought that
|
|
the drug they were using was MDA and, taking a dosage appropriate for
|
|
this, effectively overdosed themselves. He survived, following
|
|
convulsions and an extended period (several weeks) of being in a
|
|
comatose state. Tragic examples have been reported that involve
|
|
arterial vascular spasm. But in most overdose cases ascribed to DOB,
|
|
the identity of the drug has remained unestablished.
|
|
|
|
As with DOI, the presence of a heavy atom, the bromine atom, in DOB
|
|
makes the radioactive isotope labelled material a powerful research
|
|
tool. Studies with DOB labelled with either 82Br or 77Br have been
|
|
used in human subjects to follow the distribution of the drug. The
|
|
use of a whole body scanner permits the imaging of the intact body,
|
|
with the travelings of the radioactivity easily followed from outside.
|
|
A fascinating finding is that DOB goes first and foremost to the human
|
|
lung where it accumulates for a couple of hours. It is only
|
|
afterwards that the brain level builds up. There is a strong
|
|
implication that some metabolic conversion occurs in the lung, and it
|
|
is only after this that the truly active metabolite is available for
|
|
central action. This is consistent with the relatively slow onset of
|
|
effect, and the very long duration of action.
|
|
|
|
As with all the other psychedelics which can and have been studied as
|
|
their optical isomers, it is the RRS isomer of DOB that is the more
|
|
active than the racemic mixture, and the RSS is certainly much less
|
|
active, but it has never been run up to fully active levels. The
|
|
alpha-ethyl homologue of DOB is mentioned under ARIADNE. The
|
|
positionally rearranged isomers of DOB are discussed under META-DOB.

#63 DOBU; 2,5-DIMETHOXY-4-(n)-BUTYLAMPHETAMINE
|
|
|
|
SYNTHESIS: A well stirred suspension of 140 g anhydrous AlCl3 in 400
|
|
mL CH2Cl2 was treated with 102 g butyryl chloride. This mixture was
|
|
added in small portions, over the course of 20 min, to a well-stirred
|
|
solution of 110.4 g p-dimethoxybenzene in 300 mL CH2Cl2. After an
|
|
additional 1 h stirring, the mixture was poured into 1 L H2O, and the
|
|
two phases separated. The aqueous phase was extracted with 2x100 mL
|
|
CH2Cl2, and the organic fractions pooled. These were washed with
|
|
4x125 mL 5% NaOH which removed both unreacted butyric acid as well as
|
|
a small amount of 2-hydroxy-4-methoxybutyrophenone. Removal of the
|
|
CH2Cl2 under vacuum gave 156.7 g of a residue that was distilled at
|
|
170-178 !C at the water pump. The isolated 2,5-dimethoxybutyrophenone
|
|
was a pale yellow oil that weighed 146 g and was about 85% pure by GC
|
|
analysis. The principal impurity was unreacted dimethoxybenzene. The
|
|
identical preparation with CS2 as a solvent, rather than CH2Cl2 gave a
|
|
somewhat smaller yield of product.
|
|
|
|
To 150 g mossy zinc there was added a solution of 3 g mercuric
|
|
chloride in 60 mL H2O, and this was swirled periodically for 2 h. The
|
|
H2O was drained off, and the amalgamated zinc added to a 1 L
|
|
three-neck round-bottomed flask, treated with 80 mL concentrated HCl,
|
|
and heated on the steam bath. A solution of 20.8 g of
|
|
2,5-dimethoxybutyrophenone in 45 mL EtOH containing 10 mL concentrated
|
|
HCl was added in increments over a 4 h period. During this period an
|
|
additional 140 mL of concentrated HCl was added periodically to the
|
|
ketone solution. Heating was maintained for an additional 4 h. After
|
|
cooling, the aqueous filtrate was extracted with 3x100 mL CH2Cl2 and
|
|
these pooled extracts washed with 2x200 mL 5% NaOH to remove a small
|
|
amount of phenolic impurity. After removal of the solvent under
|
|
vacuum, the residual 16.1 g of clear oil was distilled over the
|
|
100-160 !C range (largely at 141-145 !C) at the water pump to give 10
|
|
g of 2,5-dimethoxy-(n)-butylbenzene as a white oil. This was about
|
|
90% pure by GC analysis, and was used without further purification in
|
|
the next step.
|
|
|
|
A mixture of 98 mL POCl3 and 108 mL N-methylformanilide was allowed to
|
|
incubate for 0.5 h. To this there was then added 47.3 g of
|
|
2,5-dimethoxy-(n)-butylbenzene and the mixture heated on the steam
|
|
bath for 1.5 h. This mixture was poured into 1 L H2O and stirred
|
|
overnight. The H2O was drained from the extremely gooey black
|
|
crystals that were formed, and extracted with 2x100 mL portions of
|
|
hexane. The black residue was diluted with these extracts and, on
|
|
slow evaporation there was deposited 26.4 g of oily amber crystals.
|
|
Filtering these through a medium porous funnel and sucking the oily
|
|
phase away from the solids yielded 14.8 g of yellow crystals that
|
|
could be recrystallized from 50 mL MeOH to give, after filtration and
|
|
air drying to constant weight, 6.4 g of
|
|
2,5-dimethoxy-4-(n)-butylbenzaldehyde as pale yellow crystals with a
|
|
mp of 47-48 !C. The recovery of all organic soluble things from the
|
|
above process gave, after removal of the extraction solvents and
|
|
making boiling hexane extractions of the residues, a second crop of
|
|
aldehyde of equal weight and of identical mp. An analytical sample,
|
|
from hexane, had the same mp. Anal. (C13H18O3) C,H.
|
|
|
|
A solution of 13.2 g 2,5-dimethoxy-4-(n)-butylbenzaldehyde in 50 mL
|
|
acetic acid was treated with 4.0 g anhydrous ammonium acetate and 10
|
|
mL nitroethane. This mixture was heated on the steam bath for 4 h,
|
|
then poured into a large quantity of H2O. This was extracted with
|
|
2x200 mL CH2Cl2, the extracts washed with H2O, and the solvent removed
|
|
to give 19 g of a deep red oil. This was dissolved in 35 mL hot MeOH
|
|
and slowly cooled, depositing yellow-orange crystals. These were
|
|
removed by filtration, washed with cold MeOH, and air-dried to
|
|
constant weight. Thus there was obtained 11.8 g of
|
|
1-(2,5-dimethoxy-4-(n)-butylphenyl)-2-nitropropene with a mp of 54-56
|
|
!C. Recrystallization of an analytical sample from MeOH tightened the
|
|
mp to 55-56 !C. Anal. (C15H21NO4) C,H,N.
|
|
|
|
To a gently refluxing suspension of 8.5 g LAH in 300 mL anhydrous Et2O
|
|
under a He atmosphere, there was added 11.0 g
|
|
1-(2,5-dimethoxy-4-(n)-butylphenyl)-2-nitropropene by allowing the
|
|
condensing ether to drip into a Soxhlet thimble containing the
|
|
nitrostyrene, thus effectively adding a warm saturated solution of it
|
|
dropwise. Refluxing was maintained overnight, and the cooled reaction
|
|
flask stirred for several additional days. The excess hydride was
|
|
destroyed by the cautious addition of 600 mL H2O containing 55 g
|
|
H2SO4. When the aqueous and Et2O layers were finally clear, they were
|
|
separated, and 250 g of potassium sodium tartrate was dissolved in the
|
|
aqueous fraction. Aqueous NaOH was then added until the pH was above
|
|
9, and this was then extracted with 3x200 mL CH2Cl2. Evaporation of
|
|
the solvent produced 12 g of an amber oil that gelatinized to a waxy,
|
|
amorphous mass. This was leached as thoroughly as possible with
|
|
anhydrous Et2O which was clarified by filtration, then saturated with
|
|
anhydrous HCl gas. After a few minutes delay, there commenced the
|
|
separation of fine white crystals of
|
|
2,5-dimethoxy-4-(n)-butylamphetamine hydrochloride (DOBU). These
|
|
weighed, after filtration, Et2O washing, and air drying to constant
|
|
weight, 5.8 g. Recrystallization from boiling CH3CN (this is an
|
|
unusually exothermic crystallization) yielded 5.4 g of a fluffy white
|
|
product with mp 151-152 !C. Anal. (C15H26ClNO2) C,H,N.
|
|
|
|
DOSAGE: uncertain.
|
|
|
|
DURATION: very long.
|
|
|
|
QUALITATIVE COMMENTS: (with 2.2 mg) It was almost the fourth hour
|
|
before I noticed something. Then I felt an increasing manic
|
|
intoxication, winding up tighter and tighter. Sleep was impossible
|
|
until some 18 hours after the start of the trial. There was some
|
|
paresthesia, but no mydriasis. This might be a stimulant, but it is
|
|
not a psychedelic, at least at this level. Go up slowly.
|
|
|
|
(with 2.8 mg) Nothing for over seven hours. Then there was what
|
|
seemed to be an irritability and shortness of temper. Mentally I am
|
|
completely clear, but no more alert than usual. There was no sleep
|
|
that evening, and the next day there was a feeling of overall
|
|
depression. Perhaps that was due to the lack of sleep, but there were
|
|
no signs of residual sleepiness.
|
|
|
|
EXTENSIONS AND COMMENTARY: It is not possible to give a dosage range
|
|
for DOBU. There is no question but that whatever is occurring is slow
|
|
of onset, and very long lived. In general, the effects resemble
|
|
stimulation more that anything else.
|
|
|
|
A butyl group has four carbons, and they can be interconnected in four
|
|
ways (as long as you donUt connect them in rings). If all four of
|
|
them are in a straight chain, you have the so-called normal butyl (or
|
|
n-butyl) group, and this is the exact arrangement that is found in the
|
|
DOBU. The atoms can be numbered #1 through #4, going outwards from
|
|
the point of attachment. The chain can, however, be only three
|
|
carbons long, and the fourth or extra carbon attached on the #2 carbon
|
|
atom; this is called the iso-butyl (or i-butyl) group. Or the extra
|
|
left-over carbon can be attached to the #1 carbon atom; this is called
|
|
the secondary butyl (or sec-butyl or s-butyl) group. Or lastly, the
|
|
atoms can be all scrunched up, with the chain only two carbons long,
|
|
and the other two left-over methyl carbons attached to the #1 carbon
|
|
atom. This isomer is called the tertiary butyl (or tert-butyl or
|
|
t-butyl) group. In animal studies, and in preliminary human studies,
|
|
the activity of these compounds drops as the butyl group gets more and
|
|
more scrunched.
|
|
|
|
The isomer with the iso-butyl group has been synthesized by the
|
|
Friedel- Crafts reaction of isobutyryl chloride with
|
|
p-dimethoxybenzene, followed by reduction of the ketone to an alcohol,
|
|
dehydration to a dimethylstyrene, and final hydrogenation to a
|
|
hydrocarbon. The formation of the benzaldehyde, reaction with
|
|
nitroethane, and final lithium aluminum hydride reduction to
|
|
2,5-dimethoxy-4-(2-methylpropyl)-amphetamine hydrochloride (DOIB, mp
|
|
164-166 !C) were completely conventional. In drug discrimination
|
|
studies in rats, DOIB was only a third as active as DOM, and in humans
|
|
the activity falls in the 10 to 15 milligram area. The isomer with
|
|
the sec-butyl group was made in a somewhat similar manner, from
|
|
2,5-dimeth-oxyacetophenone. The addition of ethyl magnesium bromide
|
|
gave an alcohol which with dehydration yielded a pair of
|
|
dimethylstyrenes isomeric to the compound mentioned above. From there
|
|
an identical sequence of steps (hydrogenation, benzaldehyde synthesis,
|
|
nitrostyrene, and lithium aluminum hydride reduction) produced
|
|
2,5-dimethoxy-4-(1-methylpropyl)amphetamine hydrochloride (DOSB, mp
|
|
168-170 !C.). In the rat studies it was only a twelfth the potency of
|
|
DOM, and in man the active dose is in the 25 to 30 milligram area. As
|
|
with the normal butyl compound, there is a strong stimulation factor,
|
|
with real and long-lasting sleep disturbance.
|
|
|
|
The last of the butyl isomers, the tert-butyl compound, was made from
|
|
a much more obvious starting material. This is the commercially
|
|
available tert-butyl hydroquinone. It was methylated in sodium
|
|
hydroxide with methyl iodide, and then carried through the above
|
|
sequence (benzaldehyde. mp 124 !C from cyclohexane, nitrostyrene,
|
|
yellow crystals from methanol, mp 95-96.5 !C, and lithium aluminum
|
|
hydride reduction) to give
|
|
2,5-dimethoxy-4-(1,1-dimethylethyl)amphetamine hydrochloride (DOTB, mp
|
|
168 !C). Rats trained in a process called the Sidman Avoidance
|
|
Schedule gave behavior that suggested that DOTB had no activity at
|
|
all, and in human trials, doses of up to 25 milligrams were totally
|
|
without effect.
|
|
|
|
An effort was made to prepare a butyl analogue containing a ring, but
|
|
it was never completed. This was the cyclopropylmethyl isomer,
|
|
2,5-dimethoxy-4-cyclo-propylmethylamphetamine hydrochloride, DOCPM.
|
|
Only the first step of its synthesis was complete (the reaction of
|
|
cyclopropylcarboxylic acid chloride with p-dimethoxybenzene) and even
|
|
it went badly. The desired ketone (2,5-dimethoxyphenyl cyclopropyl
|
|
ketone) was most difficult to separate from the recovered starting
|
|
ether. A promising approach would be the isolation of the phenol
|
|
(2-hydroxy-5-methoxyphenyl cyclopropyl ketone) which is a beautiful
|
|
yellow solid with a melting point of 99-100 !C from methanol. Anal.
|
|
(C11H12O3) C,H. It then could be methylated to the wanted
|
|
intermediate. It is the major product when the reaction is conducted
|
|
with anhydrous aluminum chloride in methylene chloride.
|
|
|
|
The 2-carbon phenethylamine homologues of these compounds could all,
|
|
in principle be easily made by using nitromethane instead of
|
|
nitroethane with the intermediary benzaldehydes. But, as of the
|
|
present time, none of them have been made, so their pharmacology
|
|
remains completely unknown.

#64 DOC; 2,5-DIMETHOXY-4-CHLOROAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 6.96 g 2,5-dimethoxyamphetamine hydrochloride
|
|
(2,5-DMA) in 250 mL H2O was made basic with aqueous NaOH and extracted
|
|
with 3x75 mL CH2Cl2. After removal of the solvent from the pooled
|
|
extracts under vacuum, the residual free base was dissolved in 36 g
|
|
glacial acetic acid and, with good stirring, cooled to 0 !C with an
|
|
external ice bath. There was then added, with a Pasteur pipette, 3 mL
|
|
of liquid chlorine. The generation of HCl was evident, and the
|
|
reaction was allowed to stir for an additional 3 h. The mixture was
|
|
then poured into 300 mL H2O and washed with 3x100 mL Et2O. The
|
|
aqueous phase was made basic with NaOH and extracted with 3x150 mL
|
|
CH2Cl2. After removal of the solvent from the pooled extracts, the
|
|
residue was dissolved in Et2O and saturated with anhydrous HCl gas.
|
|
There was the formation of a heavy oily precipitate. The ether
|
|
supernatent was decanted, and the residue was intimately mixed with
|
|
200 mL of fresh anhydrous Et2O. Everything set up as an off-white
|
|
crystalline mass weighing 2.3 g. This was dissolved in 12 mL of
|
|
boiling MeOH and diluted with 230 mL boiling Et2O. The clear solution
|
|
was quickly filtered to give a clear, pale amber mother liquor, which
|
|
soon started depositing lustrous white crystals. After filtering,
|
|
Et2O washing, and air drying to constant weight, there was obtained
|
|
1.4 g of 2,5-dimethoxy-4-chloroamphetamine hydrochloride (DOC) From
|
|
the mother liquors (from the original HCl saturation) an equal amount
|
|
of product could be obtained by exploiting the acetone insolubility of
|
|
the hydrochloride salt of the product. The published mp of this salt,
|
|
from acetone/EtOH, is 187-188 !C. A sample of this hydrochloride
|
|
salt, prepared from the amino analogue via diazotization and eventual
|
|
hydrolysis of an acetylated precursor, was recrystallized from
|
|
EtOH/ether and had a mp of 193-194.5 !C.
|
|
|
|
DOSAGE: 1.5 - 3.0 mg.
|
|
|
|
DURATION: 12 - 24 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 1.6 mg) I was hit with a slightly light
|
|
head; the effects were quite real. I was disconnected, and somehow
|
|
spacey, but this was a favorable spacey which was kind of fun.
|
|
Somewhere at about the sixth hour I realized that I was beginning to
|
|
drop off a bit, but six hours later yet, there was still a lot of
|
|
memory. This is a long thing.
|
|
|
|
(with 2.4 mg) This is what I might call an archetypical psychedelic.
|
|
Everything is there in spades, with few if any of the subtle graces,
|
|
the Tgentle imagesU and Tgentle fantasiesU of the 2-carbon
|
|
phenethylamines. This is the works. There are visuals, and there are
|
|
interpretive problems with knowing just where you really are. The
|
|
place where nothing makes sense, and yet everything makes sense. I
|
|
have just slept for a few hours, and now I am awake and it has been
|
|
eighteen hours, and there is a lot still going on, although I have a
|
|
relaxed, good feeling. Anyone who uses this had better have 24 hours
|
|
at their disposal.
|
|
|
|
(with 2.4 mg) Here I am at the sixth hour, and I am still roaring
|
|
along at a full plus three. I have established that this material is
|
|
neither anti-erotic nor anorexic. The body is very comfortable, and
|
|
so is the mind. There is an interesting aspect, perhaps peculiar only
|
|
to this experiment and under these conditions. With my eyes closed
|
|
the fantasy is a completely dark screen, lovely and seductive, subtle,
|
|
and yet light must be deliberately brought in. This is not in any way
|
|
negative for being in the dark, but is just unusual. I will have to
|
|
try this in the daylight next time, to see what the eyes-closed brings
|
|
to the mind-screen. At 24 hours, I have found that my sleep was not
|
|
too great. My dreams were tight, and I kept defending against
|
|
trouble; the nervous system was too alert. I was in a good humor,
|
|
though, and I still am. This is excellent stuff, but start early in
|
|
the day.
|
|
|
|
EXTENSIONS AND COMMENTARY: It is clear that the three halo-amphetamine
|
|
derivatives, DOI, DOB and DOC, are all pretty much of the same
|
|
potency. And all of them very long lived. The difference between the
|
|
various halogen atoms was brought up under the 2C-C discussion. DOC
|
|
is clearly a long-lasting, dyed-in-the-wool psychedelic.
|
|
|
|
In the making of this, by the procedures that have been followed in
|
|
Canada, there are two chemical intermediates which might, some day, be
|
|
looked at as potential psychedelics under their own colors. Reduction
|
|
of the compound that is called DON in this Book II
|
|
(2,5-dimethoxy-4-nitroamphetamine hydrochloride) with Pd/charcoal and

hydrogen, gives the 4-amino derivative. This is
|
|
2,5-dimethoxy-4-aminoamphetamine dihydrochloride, DOA, which melts at
|
|
248-250 !C. And the reduction of an oxime intermediate gives rise to
|
|
the acetamido analogue, 2,5-dimethoxy-4-acetamidoamphetamine
|
|
hydrochloride, DOAA, with a mp of 249-250 !C. Neither compound has
|
|
been tasted, but someday this omission will be corrected. DOA and
|
|
DOAA have a sinister ring to them, however, and some changes of
|
|
terminology might be needed. DOA, in the coroner's vocabulary, means
|
|
Dead-On-Arrival. But then, AMA (the American Medical Association)
|
|
just happens to also mean (in the jargon of emergency medicine)
|
|
Against-Medical-Advice. Everything averages out, somehow. Remember
|
|
that the amyl homolog (amyl at the 4-position) follows the 4-letter
|
|
convention of all of the DOM homo-logues, and has the code name of
|
|
DOAM. Thus, DOA, amino; DOAA, acetamido, and DOAM, amyl.

One must learn to keep one's sense of humor. The immortal humorist
|
|
Wavy Gravy once said, RIf you canUt laugh at life, it just isnUt funny
|
|
anymore.S The code name of this compound,
|
|
2,5-dimethoxy-4-chloroamphetamine is, after, all, DOC. This should
|
|
certainly appeal to some physicians.

#65 DOEF; 2,5-DIMETHOXY-4-(2-FLUOROETHYL)-
|
|
|
|
AMPHETAMINE
|
|
|
|
SYNTHESIS: A well-stirred solution of 0.45 g free base DOB in 2 mL
|
|
CH2Cl2 was treated with 0.37 g triethylamine, cooled to 0 !C, and
|
|
there was then added a solution of 0.39 g
|
|
1,1,4,4-tetramethyl-1,4-dichlorodisilylethylene in 2 mL CH2Cl2. The
|
|
reaction mixture was allowed to return to room temperature, with
|
|
stirring continued for 2 h. The solvent was removed under vacuum, the
|
|
residue suspended in hexane, and the insoluble by-products removed by
|
|
filtration through celite. Removal of the solvent under vacuum gave
|
|
0.60 g
|
|
1-(4-bromo-2,5-dimethoxyphenyl)-2-(1-aza-2,5-disila-2,2,5,5-tetramethylcyclopentyl)propane
|
|
as a gold-colored impure semi-solid mass which was used without
|
|
further purification.
|
|
|
|
To a solution of 0.60 g
|
|
1-(4-bromo-2,5-dimethoxyphenyl)-2-(1-aza-2,5-disila-2,2,5,5-tetramethylcyclopentyl)propane
|
|
in 10 mL anhydrous Et2O under an inert atmosphere and cooled to -78 !C
|
|
there was added 1.8 mL of a 1.7 M solution of t-butyl lithium in
|
|
hexane. The resulting yellow solution was stirred for 20 min, and
|
|
then treated with 1.65 mL of a 1.4 M solution of ethylene oxide in
|
|
Et2O, the stirring was continued for 40 min, then the reaction mixture
|
|
allowed to come to room temperature over an additional 40 min. There
|
|
was added 20 mL hexane, and the temperature increased to 50 !C for an
|
|
additional 2 h. The reaction mixture was treated with 3 mL H2O and
|
|
diluted with 60 mL Et2O. The organic phase was washed with saturated
|
|
NH4Cl, dried over anhydrous MgSO4, and after filtering off the
|
|
inorganic drying agent, the organic solvents were removed under
|
|
vacuum. The gold-colored residual oil was dissolved in 10 mL MeOH and
|
|
treated with a 10% KOH. This mixture was heated for 30 min on the
|
|
steam bath, returned to room temperature, and the volatiles removed
|
|
under vacuum. The residue was dissolved in 3% H2SO4, washed twice
|
|
with CH2Cl2, brought to pH 12 with 25% NaOH, and extracted with 3x50
|
|
mL CH2Cl2. The pooled extracts were combined, dried with anhydrous
|
|
Na2SO4, and the solvent removed under vacuum to give 0.24 g of
|
|
2,5-dimethoxy-4-(2-hydroxyethyl)amphetamine (DOEH) as a white solid
|
|
with a mp of 102-104 !C.
|
|
|
|
To a suspension of 0.94 g DOEH in ice-cold anhydrous Et2O containing
|
|
1.4 g triethylamine, there was added 2.4 g trifluoroacetic anhydride
|
|
dropwise over the course of 10 min. The reaction mixture was brought
|
|
to reflux temperature, and held there with stirring for 1 h. After
|
|
cooling, 60 mL of CH2Cl2 was added, and the organic phase washed with
|
|
saturated NaHCO3. The solvent was removed under vacuum, providing a
|
|
gold-colored solid as a residue. This was dissolved in 50 mL MeOH,
|
|
diluted with 30 mL H2O and, following the addition of 0.76 g solid
|
|
NaHCO3 the reaction mixture was stirred at room temperature for 3 h.
|
|
The excess MeOH was removed under vacuum, and the remaining solids
|
|
were suspended in CH2Cl2 and washed with H2O. After drying the
|
|
organic phase with anhydrous Na2SO4 and removal of the solvent under
|
|
vacuum, there was obtained 1.34 g
|
|
1-(2,5-dimethoxy-4-(2-hydroxyethyl)phenyl)-2-(2,2,2-trifluoroacetamido)propane
|
|
as white solid with a mp of 129-131 !C. Anal. (C15H20F3NO4) C,H.
|
|
|
|
A well-stirred solution of 0.09 g
|
|
1-(2,5-dimethoxy-4-(2-hydroxyethyl)phenyl)-2-(2,2,2-trifluoroacetamido)propane
|
|
in 15 mL CH2Cl2 was cooled to -78 !C and treated with 0.05 g
|
|
diethylaminosulfur trifluoride (DAST) added dropwise. The pale yellow
|
|
reaction solution was stirred an additional 5 min and then brought up
|
|
to room temperature and stirred for 1 h. There was then added
|
|
(cautiously) 3 mL H2O followed by additional CH2Cl2. The phases were
|
|
separated, the organic phase washed with H2O, dried with anhydrous
|
|
Na2SO4 and, after filtering off the drying agent, stripped of solvent
|
|
under vacuum. There was thus obtained 0.088 g of
|
|
1-[2,5-dimethoxy-4-(2-fluoroethyl)phenyl]-2-(2,2,2-trifluoroacetamido)propane
|
|
as a white solid with a mp of 102-104 !C.

|
1-[2,5-dimethoxy-4-(2-hydroxyethyl)phenyl]-2-(2,2,2-trifluoroacetamido)propane
|
|
in a mixture of 5 mL CH2Cl2 and 5 mL IPA was treated with 0.2 mL 2 N
|
|
KOH, heated on the steam bath for 30 min, and then stripped of
|
|
solvents under vacuum. The residue was suspended in CH2Cl2 and washed
|
|
with 20% NaOH. The organic phase was dried with anhydrous Na2SO4
|
|
which was removed by filtration, and the combined filtrate and
|
|
washings stripped of solvent under vacuum. The residual glass (0.08
|
|
g) was dissolved in IPA, neutralized with concentrated HCl and diluted
|
|
with anhydrous Et2O to provide
|
|
2,5-dimethoxy-4-(2-fluoroethyl)amphetamine hydrochloride (DOEF) as a
|
|
white crystalline solid with a mp of 205-208 !C. Anal. (C13H21ClFNO2)

DURATION: 12 - 16 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 2.2 mg) Somewhere between the first and
|
|
second hour, I grew into a world that was slightly unworldly. Why?
|
|
That is hard to say, as there was no appreciable visual component. I
|
|
just knew that the place I was in was not completely familiar, and it
|
|
was not necessarily friendly. But it was fascinating, and the music
|
|
around me was magical. Time was moving slowly. I had to drive across
|
|
the bay at about ten hours into this, and I was comfortable. That
|
|
evening I slept well, but my dreams were pointless.
|
|
|
|
(with 3.0 mg) It took almost three hours to full activity. The first
|
|
signs of effects were felt within a half hour, but from then on the
|
|
progress was slow and easy, without any discernible jumps. There was
|
|
absolutely no body discomfort at all. Completely comfortable. There
|
|
was a general humorousness about my state of mind which is always a
|
|
good sign. We went to the bedroom at the two and a half hour point,
|
|
and proceeded to establish that the material is far from anti-erotic.
|
|
Beautiful response, without a mention of any feeling of risk at
|
|
orgasm. I myself was not able to reach orgasm until about 5th to 6th
|
|
hour, and then it was full and exceptionally delicious. So was the
|
|
second one, a couple of hours later, if I remember correctly. All
|
|
systems intact, body, mind and emotion. Gentle. Good for writing.
|
|
No dark corners apparent at all. For me, not highly visual. Would
|
|
take again, higher.
|
|
|
|
(with 3.0 mg) There was no body threat at any time Q very
|
|
comfortable. Good eyes closed, with complex imagery to music, but not
|
|
too much with eyes-open. My attention span is relatively short, and
|
|
easily diverted into new directions Q all quite reminiscent of DOI
|
|
both as to dosage and effect. At 13 hours, I am still too alert to
|
|
sleep, but a couple of hours later, OK. In the morning there is still
|
|
a trace of something going on. This was a valid +++.
|
|
|
|
EXTENSIONS AND COMMENTARY: I was asked by a student of mine a while
|
|
ago, when I told him of this material, just why would anyone just
|
|
happen to place a fluorine atom at the end of the 4-ethyl group of
|
|
DOET? It wasnUt the sort of thing that someone would just happen to
|
|
do. If there were a rationale, then that's fine. But by capricious
|
|
impulse, no. But there is a rationale of sorts, which I just hinted
|
|
at in the discussion under 2C-T-21.
|
|
|
|
This argument of reason goes as follows. Assume that I would like to
|
|
put a fluorine atom into a drug that does not normally have one. Why
|
|
would I want to? Because I want to have the molecule carry a
|
|
radioactive fluorine atom into some inner recess of the brain. Why?
|
|
Because by using a positron-emitting fluorine I could possibly
|
|
visualize the area of the brain that the drug went to. And if it went
|
|
there in some abnormal way, the exact measure of that abnormality
|
|
might give some clue as to potential brain misfunctioning.
|
|
|
|
But, if you put a fluorine atom on a drug, it becomes a totally new
|
|
drug and, quite reasonably, a pharmacologically different drug.
|
|
However, a body of evidence is being accumulated that if a halogen,
|
|
such as a bromine or an iodine atom, is replaced by a beta-fluoroethyl
|
|
group, the electronic and polar properties of the drug can be pretty
|
|
much the same. So, what psychedelics have a bromo or an iodo group?
|
|
Obviously, DOB and DOI. Thus, DOEF is a natural candidate for
|
|
fluorine-18 positron emission tomography, and also a natural candidate
|
|
for clinical trials. And, voila, it is an active material.
|
|
|
|
And IUll bet you dollars to doughnuts, that if one were to make the
|
|
two-carbon analog 2,5-dimethoxy-4-(2-fluoroethyl)-phenethylamine, it
|
|
would be every bit as much a treasure and ally as is 2C-B or 2C-I. In
|
|
fact, I am sure enough about this prediction that I am willing to name
|
|
the stuff 2C-EF. It will be easily made from 2C-B by the same
|
|
reaction scheme that was used above for DOEF. And I will even guess
|
|
that its activity level will be in the 20-30 milligram area.

#66 DOET; HECATE; 2,5-DIMETHOXY-4-ETHYLAMPHETAMINE
|
|
|
|
SYNTHESIS: To a solution of 19.7 g 2,5-dimethoxy-4-ethylbenzaldehyde
|
|
(see the recipe for 2C-E for its preparation) in 72 g glacial acetic
|
|
acid there was added 6.5 g anhydrous ammonium acetate and 10.2 g
|
|
nitroethane. After heating for 1.75 h on the steam bath, the reaction
|
|
mixture was cooled in a wet ice bath, diluted with 10 mL H2O, and
|
|
seeded with a small crystal of product. The yellow crystals were
|
|
removed by filtration (7.6 g wet with acetic acid) and another 2.25 g
|
|
was obtained from the mother liquors with additional H2O. The
|
|
combined fractions were recrystallized from 25 mL boiling MeOH, to
|
|
give 6.5 g fine yellow crystals of
|
|
1-(2,5-dimethoxy-4-ethyl)-2-nitropropene, with a mp of 67.5-68.5 !C.
|
|
Anal. (C13H17NO4) C,H,N.
|
|
|
|
A suspension of 6.5 g LAH in 500 mL well stirred anhydrous Et2O was
|
|
held at reflux under an inert atmosphere, with the return of the
|
|
condensed solvent passing through a Soxhlet thimble containing 6.5 g
|
|
1-(2,5-dimethoxy-4-ethylphenyl)-2-nitropropene. After the addition of
|
|
the nitrostyrene was complete, the stirred suspension was maintained
|
|
at reflux for an additional 18 h, then cooled to room temperature.
|
|
The excess hydride was destroyed with 500 mL 8% H2SO4, added
|
|
cautiously until the hydrogen evolution ceased, then at a speed that
|
|
allowed the formed solids to disperse. The phases were separated, the
|
|
aqueous phase washed once with Et2O, treated with 150 g potassium
|
|
sodium tartrate, and finally made basic (pH >9) with 5% NaOH. This
|
|
was extracted with 3x100 mL CH2Cl2, the extracts pooled, and the
|
|
solvent removed under vacuum. The residue, 7.9 g of a clear oil, was
|
|
dissolved in 100 mL anhydrous Et2O and saturated with anhydrous HCl
|
|
gas. After standing at room temperature for 2 h, the crystalline
|
|
2,5-dimethoxy-4-ethylamphetamine hydrochloride (DOET) was removed by
|
|
filtration, washed with Et2O, and air dried to constant weight. There
|
|
was obtained 5.9 g of lustrous white crystal with a mp of 190-191 !C.
|
|
Recrystallization from CH3CN or EtOAc increased the mp to 194-195 !C.
|
|
Anal. (C13H22ClNO2) C,H,N.
|
|
|
|
DOSAGE: 2 - 6 mg.
|
|
|
|
DURATION: 14 - 20 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 1.0 mg) This was a very gentle, relaxing
|
|
level, but there were no psychedelic effects that were apparent.
|
|
Easy, and relaxed, and I am in no way intoxicated or turned on. But I
|
|
was in the throes of my menstrual period, and the cramps (and the
|
|
accompanying irritability) were completely knocked out. Perhaps this
|
|
is why I felt so relaxed and at peace.
|
|
|
|
(with 2.5 mg) There is much, too much, movement with my eyes closed.
|
|
And an awful lot there with my eyes open. The movement on the
|
|
concrete floor in the basement when I went downstairs for wood for the
|
|
fireplace, was too much. I felt almost sea-sick. And I am having
|
|
reality problems Q I cannot seem to find my centering point of
|
|
reference. There has to be a place to pin myself down to, and it is
|
|
not findable anywhere I look. And my legs are twitching, and feeling
|
|
as if they are falling asleep, and I had a crawling sensation on my
|
|
body, so the body is not at peace either. In the morning I was still
|
|
++, but there is a clear indication that I am repairing. Anyway, I
|
|
survived the experience. This is definitely not my thing.
|
|
|
|
(with 4 mg) Just after an hour into the experiment, I was surprised
|
|
by the awareness of some effects Q I had forgotten that I had taken
|
|
something. At the second hour, it was real, but subtle. As a
|
|
psychotomimetic or STP-like thing, there is very little there. But as
|
|
a mood energizer, it is really a ++ or more. The clinical literature
|
|
is right Q none of the hallucinogenic effects, but one brings into
|
|
play whatever one wants to. Worked at cleaning up the office until 11
|
|
PM. I slept well. This has none of the LSD or STP seriousness.
|
|
|
|
(with 6 mg) The onset was slow, and subtle. But the effects are
|
|
fully there in about three or so hours. Everything I smelled was
|
|
vivid, as are all the colors and shapes; they are clean, beautiful,
|
|
serenely self-contained. No visual movement. The eyes-closed fantasy
|
|
images tend to take off on their own, however, and they are extremely
|
|
rich. I donUt see any dark corners. I believe it might well be
|
|
possible to be creative with this, and there is no suggestion of body
|
|
depletion, of body load.
|
|
|
|
(with 7 mg) A hot day. Unbelievably lovely erotic-to-divine, deep
|
|
loving, open, not much visual, eyes-closed form-image-symbol. Sleep
|
|
attempts very shallow, slight TthinnessU, with an anticipation of
|
|
darts. Intellect and feeling-emotion area intact and functioning at
|
|
all times. Next morning still at a plus one. Incredible material.
|
|
Perhaps best at 6 to 7 milligrams, no higher due to body load.
|
|
|
|
EXTENSIONS AND COMMENTARY: The original code for this compound was
|
|
DOE, which was completely logical based on DOM being the methyl member
|
|
of this series (DO for the removal of the oxygen, desoxy, and M for
|
|
putting a methyl in its place). And the putting of the ethyl thence
|
|
should be DOE. This was fine until it was pointed out to me by a
|
|
close colleague that DOE was a classic abbreviation for
|
|
desoxyephedrine, a synonym for methamphetamine. The pressure to add
|
|
the RTS of the RETS of the ethyl was heightened by looking ahead to
|
|
other members of the series. DOA became DOAM, DOE became DOET, but
|
|
DOM was already too firmly set in popular usage. And, anyway, DOME
|
|
really looked strange.
|
|
|
|
The original publications of the action of DOM clearly documented the
|
|
compound as being a psychedelic and one with a sizeable measure of
|
|
potential abuse. And, it is not a surprise that it was quickly
|
|
shuffled into a legal classification that effectively precluded any
|
|
further study of it. So, when this immediate homologue of DOM was
|
|
studied and discussed in the literature, all reported dosages were
|
|
those that were at the lowest levels, and no disturbing hints of
|
|
abusability were mentioned. And this particular homologue has so far
|
|
escaped the attention and restrictive action of the drug enforcement
|
|
agencies, although the specific wording of the Controlled Substance
|
|
Analogue Enforcement Act of 1986 might make this point moot, at least
|
|
as far as human trials are concerned. At modest levels, DOET has the
|
|
reputation of being a cognitive enhancer and is largely free of those
|
|
sensory distortions that would catch the attention of the authorities
|
|
who cannot tolerate drugs that distort the senses. The higher levels
|
|
mentioned here have never been put into the published literature. It
|
|
must be noted that there is a considerable variation of individual
|
|
responses to this material. The effective dose range stated is quite
|
|
broad. Some people are quite sensitive. This is, after all, one of
|
|
the Classic Ladies, namely HECATE.
|
|
|
|
The young experimental subject who had the dramatic relief from
|
|
menstrual cramps at the one milligram dose tried the compound again
|
|
the following month, and again had complete relief. But another
|
|
volunteer, also plagued with severe cramping at that particular time
|
|
of month, found no relief at all. A 50% success rate. No one else
|
|
has, to my knowledge, explored this particular property.

#67 DOI; 2,5-DIMETHOXY-4-IODOAMPHETAMINE
|
|
|
|
SYNTHESIS: A mixture of 14.8 g phthalic anhydride and 19.5 g of
|
|
2,5-dimethoxyamphetamine (2,5-DMA) as the free base was heated
|
|
gradually to about 150 !C with an open flame. A single clear phase
|
|
was formed with the loss of H2O. After the hot melt remained quiet
|
|
for a few moments, it was allowed to cool to about 50 !C and then
|
|
diluted with 100 mL of hot MeOH. The solution was stirred until
|
|
homogenous, seeded with product, and then cooled in an ice bath to
|
|
complete the crystallization. After removal of the product by
|
|
filtration, washing sparingly with MeOH, and air drying, there was
|
|
obtained 24.6 g of N-(1-(2,5-dimethoxyphenyl)-2-propyl)phthalimide as
|
|
off-white crystals, with a mp of 105-106 !C. Anal. (C19H19NO4) C,H,N.
|
|
|
|
To a solution of 2.0 g N-(1-(2,5-dimethoxyphenyl)-2-propyl)phthalimide
|
|
in 15 mL warm acetic acid which was being vigorously stirred, there
|
|
was added a solution of 1.2 g iodine monochloride in 3 mL acetic acid.
|
|
This was stirred for 2 h at about 40 !C during which time there was a
|
|
definite lightening of color, but no solids formed. The reaction
|
|
mixture was poured into 600 mL H2O which produced a reddish glob
|
|
floating in a yellow-orange opaque aqueous phase. The glob was
|
|
physically removed, dissolved in 30 mL boiling MeOH which, on cooling
|
|
in an ice bath, deposited off-white crystals. These were removed by
|
|
filtration, washed with MeOH, and air dried to give 1.5 g of
|
|
N-[1-(2,5-dimethoxy-4-iodophenyl)-2-propyl]phthalimide as fine white
|
|
crystals with a slight purple cast. The mp was 103-105.5 !C and the
|
|
mixed mp with the starting non-iodinated phthalimide (mp 105-106 !C)
|
|
was depressed (85-98 !C). Extraction of the aqueous phase, after
|
|
alkalinification, provided an additional 0.15 g product. Anal.
|
|
(C19H18NO4) C,H,N.
|
|
|
|
A solution of 0.75 g
|
|
N-(1-(2,5-dimethoxy-4-iodophenyl)-2-propyl)phthalimide in 10 mL EtOH
|
|
was treated with 0.3 mL of hydrazine hydrate, and the clear solution
|
|
was held at reflux on the steam bath overnight. After cooling, there
|
|
was a crystallization of 1,4-dihydroxyphthalizine that started as
|
|
small beads but finally became extensive and quite curdy. These
|
|
solids were removed by filtration and had a mp of about 340 !C
|
|
(reference samples melted over a five to ten degree range in the area
|
|
of 335-350 !C). The filtrate was dissolved in 100 mL CH2Cl2 and
|
|
extracted with 2x150 mL 0.1 N HCl. The aqueous extracts were washed
|
|
once with CH2Cl2, made basic with 5% NaOH, and extracted with 3x100 mL
|
|
CH2Cl2. Removal of the solvent under vacuum gave 0.5 g of a colorless
|
|
oil which was dissolved in 300 mL anhydrous Et2O and saturated with
|
|
anhydrous HCl gas. There was obtained, after filtration, and air
|
|
drying, 0.35 g of 2,5-dimethoxy-4-iodoamphetamine hydrochloride (DOI)
|
|
as white crystals that melted at 200.5-201.5 !C. This value did not
|
|
improved with recrystallization. Anal. (C11H17ClINO2) C,H,N.

|
|
|
DOSAGE: 1.5 - 3.0 mg.
|
|
|
|
DURATION: 16 - 30 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 0.6 mg) There was a nice spacey
|
|
light-headedness for a few hours, and time seemed to move quite
|
|
slowly. Then a generic sadness came over me, as I reminisced about
|
|
earlier days (recalling pleasures now gone) and wondered if I would be
|
|
allowed to be here on the Farm when I am old and not important. There
|
|
is so much to be done, and I cannot do it all, and no one else cares.
|
|
My mood became present-day and healthy by about the seventh hour.
|
|
|
|
(with 1.6 mg) The general nature of the experience was depressing,
|
|
with a sad view of life. There was no way I could connect with my
|
|
emotions. Even my sadness was vague. At about the ninth hour I
|
|
decided that enough was enough, and this strangely disappointing
|
|
about-plus-two was aborted with 125 micrograms of LSD. The emotions
|
|
became present and living within a half hour. I was greatly relieved.
|
|
The erotic was not a mechanical attempt but a deeply involved feeling
|
|
with an archetype of orgasm easily available. It was shaped like a
|
|
flower, richly colored, with an unusual RSS shape to it. This was a
|
|
lovely end to a difficult day.
|
|
|
|
(with 3.0 mg) This is a clear, clean psychedelic. The eyes-closed
|
|
imagery is excellent, with clearly delineated patterns, pictures, and
|
|
colors. Perfect for an artist, and next time IUll devote some time to
|
|
painting. Total ease for the body, but no help for my smoking
|
|
problem. I still want to smoke. And at sixteen hours into this I am
|
|
still at 1.5+ but IUll try to go to bed anyway, and sleep.
|
|
|
|
(with 3.5 mg) I was at a full crashing +++ for about three or four
|
|
hours. There was none of the LSD sparkle, but there were moments of
|
|
Tlight-headednessU where one could move sideways with reality. I
|
|
could leave where I was right over there, and come over here and get a
|
|
strange but authentic view of where the TthereU was that I had left.
|
|
It would be out-of-body, except that the body came over here with me
|
|
rather than staying there. This doesnUt make sense now, but it sure
|
|
did then. There was no trace of body impact, and I slept late that
|
|
evening, but with some guardedness due to the intense imagery. This
|
|
was no more intense than with 3.0 milligrams, but it was a little bit
|
|
more to the unreal side.
|
|
|
|
(with 1.0 mg of the RRS isomer) There was a clear ++ from the second
|
|
to the eighth hour, but somehow there was not quite the elegance or
|
|
the push of the racemate. I was sensible, and managed to do several
|
|
technical chores in a reasonable way. Easy sleep at 15 hours into
|
|
it.
|
|
|
|
(with 2.3 mg of the RRS isomer) The water solution of the
|
|
hydrochloride salt has a slightly sweetish taste! I was at a +++
|
|
without question, but there was a slight down mood towards the end.
|
|
And it lasted a really long time; I was distinctly aware of residual
|
|
stuff going on, well into the next day.
|
|
|
|
(with 6.3 mg of the RSS isomer) I was at a benign one-and-a-half plus
|
|
at about two hours, and finally flattened out at a ++. Would I double
|
|
this dose? Probably not, but half again (to 9 or 10 milligrams) would
|
|
feel safe for a plus 3. By evening I was near enough baseline to
|
|
drive into town for a social obligation, but even when trying to sleep
|
|
later that night there was some residue of imagery; remarkably, it was
|
|
all in slow motion. The fantasies were slow-paced and sluggish. It
|
|
would have been interesting to have explored eyes-closed during the
|
|
day.
|
|
|
|
EXTENSIONS AND COMMENTARY: Again, as with every other psychedelic
|
|
amphetamine analogue which has a chiral center and has been explored
|
|
as the individual optical isomers, it is the RRS isomer that is the
|
|
more potent. And again, the other isomer, the RSS isomer, still shows
|
|
some activity. The same was true with DOB, and DOM, and MDA. The
|
|
only exception was MDMA, but then that is more of a stimulant, and
|
|
there is virtually no psychedelic component to its action. Rat
|
|
studies, where there is a measure of the discrimination of a test
|
|
compound from saline, have shown the RRS isomer to have about twice
|
|
the potency of the RSS isomer. That the RRS is more potent is
|
|
certain, but the above reports would suggest that the factor would be
|
|
closer to times-four rather than times-two.
|
|
|
|
A number of studies with DOI in animal models have shown it to have an
|
|
extremely high binding capacity to what are called the 5-HT2
|
|
receptors. Serotonin is a vital neurotransmitter in the brain, and is
|
|
strongly implicated in the action of all of the phenethylamine
|
|
psychedelics. The place where it acts, at the molecular level, is
|
|
called its receptor site. As an outgrowth of the cooperative studies
|
|
of the medicinal chemists working closely with the
|
|
neuropharmacologists, a number of compounds have emerged that interact
|
|
with these sites. But this one interacts with these sites and not
|
|
those, and that one interacts with those sites and not these. So,
|
|
there has developed a collection of sub-divisions and sub-subdivisions
|
|
of receptor sites, all related to serotonin, but each defined by the
|
|
particular compound that interacts most tightly with it.
|
|
|
|
Thus, there were serotonin R1S receptors, and then there were R1S and
|
|
R2S receptors, and then R1a and R1bS and R2aS and R2bS receptors, and
|
|
on and on. These are called 5-HT receptors, since the chemical name
|
|
for serotonin is 5-hydroxytryptamine, and the scientist would never
|
|
want to let the layman know just what he is talking about. DOI has
|
|
been synthesized with a variety of radioactive iodine isotopes in it,
|
|
and these tools have been of considerable value in mapping out its
|
|
brain distribution. And by extrapolation, the possible localization
|
|
of other psychedelic compounds that cannot be so easily labelled. A
|
|
small neurochemical research company on the East Coast picked up on
|
|
these properties of DOI, and offered it as a commercial item for
|
|
research experiments. But I doubt that they are completely innocent
|
|
of the fact that DOI is an extremely potent psychedelic and that it is
|
|
still unrecognized by the Federal drug laws since, in their most
|
|
recent catalog, the price had almost doubled and a note had been added
|
|
to the effect that telephone orders cannot be accepted for this
|
|
compound.
|
|
|
|
The four-carbon butylamine homologue (the ARIADNE analogue) of DOI has
|
|
been synthesized. A mixture of the free base of
|
|
1-(2,5-dimethoxyphenyl)-2-aminobutane (see preparation under DOB) and
|
|
phthalic anhydride was fused, cooled, and recrystallized from either
|
|
methanol or cyclohexane to give crystals of
|
|
N-[1-(2,5-dimethoxyphenyl)-2-butyl]phthalimide with a melting point of
|
|
76-77 !C and an analysis (C20H21NO4) C,H,N. This was iodinated with
|
|
iodine monochloride in acetic acid to give
|
|
N-[1-(2,5-dimethoxy-4-iodophenyl)-2-butyl]phthalimide which was
|
|
chromatographically distinct from the uniodinated starting material
|
|
(silica gel, CH2Cl2 ), but which did not crystallize. This was
|
|
treated with hydrazine hydrate in ethanol to provide
|
|
1-(2,5-dimethoxy-4-iodophenyl)-2-aminobutane hydrochloride which was
|
|
crystallized from CH3CN/EtOH to give white crystals with a mp of
|
|
217-218.5 !C and an analysis (C12H19CINO2) C,H,N. This butyl homolog
|
|
of DOI has been assayed at up to four milligrams, and is without any
|
|
central effects whatsoever. An experiment with 12.4 microcuries of
|
|
131I labelled material with the whole body scanner showed most of it
|
|
accumulating in the gut and liver, with almost none to the brain.
|
|
|
|
For those who find such statistics interesting, the parent compound
|
|
DOI vies with DOB as probably the most potent of the phenethylamine
|
|
psychedelics as of the moment, and certainly one of the most long
|
|
lived.
|
|
|
|
A very important, centrally pivotal, and completely paradoxical
|
|
compound in this area, is the N,N-dimethyl homologue of DOI, or
|
|
2,5-dimethoxy-N,N-dimethyl-4-iodoamphetamine (IDNNA). This compound
|
|
was the starting point of the study of a large number of homologues
|
|
and it deserves, and has received, a separate recipe.

#68 DOM; STP; 2,5-DIMETHOXY-4-METHYLAMPHETAMINE
|
|
|
|
SYNTHESIS: To a solution of 54.9 g 2,5-dimethoxy-4-methylbenzaldehyde
|
|
(see the recipe for 2C-D for its preparation) in 215 g glacial acetic
|
|
acid there was added 19.5 g anhydrous ammonium acetate and 30.6 g
|
|
nitroethane. This mixture was heated for 3 h on the steam bath, the
|
|
reaction mixture was cooled in a wet ice bath, allowing the
|
|
spontaneous formation of yellow crystals. As much H2O as possible was
|
|
added (just short of a persistant cloudy oily character) and after a
|
|
few additional h standing, the crystalline
|
|
1-(2,5-dimethoxy-4-methylphenyl)-2-nitropropene was removed by
|
|
filtration and recrystallized from boiling acetic acid. The yield,
|
|
after drying to constant weight, was 28.3 g and the mp was 87-88 !C.
|
|
Anal. (C12H15NO4) C,H,N.
|
|
|
|
A suspension of 9.5 g LAH in 750 mL well stirred anhydrous Et2O was
|
|
held at reflux under an inert atmosphere, with the return of the
|
|
condensed solvent passing through a Soxhlet thimble containing 9.5 g
|
|
1-(2,5-dimethoxy-4-methylphenyl)-2-nitropropene. After the addition
|
|
of the nitrostyrene was complete, the stirred suspension was
|
|
maintained at reflux for an additional 4 h, then cooled to room
|
|
temperature and allowed to continue stirring overnight. The excess
|
|
hydride was destroyed by the addition of 750 mL 8% H2SO4, cautiously,
|
|
until the hydrogen evolution ceased, then at a speed that allowed the
|
|
formed solids to disperse. The phases were separated, the aqueous
|
|
phase washed once with Et2O, treated with 225 g potassium sodium
|
|
tartrate, and finally made basic (pH >9) with 5% NaOH. This was
|
|
extracted with 3x150 mL CH2Cl2, the extracts pooled, and the solvent
|
|
removed under vacuum. The residue was 9.6 g of a clear oil which
|
|
spontaneously formed crystals with a mp of 60.5-61 !C from hexane.
|
|
These solids were dissolved in 150 mL anhydrous Et2O, and saturated
|
|
with anhydrous HCl gas. After standing at room temperature for 2 h,
|
|
the crystalline 2,5-dimethoxy-4-methylamphetamine hydrochloride (DOM)
|
|
was removed by filtration, washed with Et2O, and air dried to constant
|
|
weight. There was obtained 8.25 g of glistening white crystals that
|
|
had a mp of 190.5-191.5 !C. The sulfate had a mp of 131 !C. Anal.
|
|
(C12H20ClNO2) C,H,N.
|
|
|
|
The above nitrostyrene may also be converted to the final amine
|
|
product through the intermediary of the corresponding phenylacetone.
|
|
To a well stirred suspension of 10.4 g powdered iron in 20 mL glacial
|
|
acetic acid held at reflux temperature, there was added 4.9 g
|
|
1-(2,5-dimethoxy-4-methylphenyl)-2-nitropropene as a solid. Refluxing
|
|
was continued for 2 h and then all was filtered through wet Celite.
|
|
After washing with 300 mL H2O followed by 300 mL Et2O, the combined
|
|
filtrate and washes were separated, and the aqueous phase extracted
|
|
with 2x100 mL Et2O. The organic phase and extracts were combined and
|
|
washed with 2x100 mL saturated K2CO3 and the solvent was removed under
|
|
vacuum yielding a reddish oil weighing 3.3 g. This was distilled at
|
|
111-115 !C at 0.5 mm/Hg to give a pale green solid. After
|
|
recrystallization from benzene, there was obtained 2.8 g
|
|
1-(2,5-dimethoxy-4-methylphenyl)-2-propanone as white crystals with a
|
|
mp of 57-59 !C. This ketone has also been described as a pale-yellow
|
|
oil with a bp of 115-118 !C at 0.4 mm/Hg. A solution of 0.7 g
|
|
1-(2,5-dimethoxyphenyl-4-methyl)-2-propanone in 20 mL MeOH was treated
|
|
with 6.0 g ammonium acetate, 0.3 g sodium cyanoborohydride, and 3 g
|
|
Linde 3 A molecular sieves. The mixture was stirred overnight, the
|
|
solids removed by filtration, and the filtrate dissolved in 100 mL
|
|
H2O. The solution was acidified with dilute H2SO4, and washed with
|
|
2x25 mL CH2Cl2. The aqueous phase was made basic with aqueous NaOH,
|
|
and the product extracted with 2x25 mL CH2Cl2. The solvent was
|
|
removed under vacuum, and the residue distilled (at 160 !C at 0.2
|
|
mm/Hg) to give colorless product which was dissolved in 3 mL IPA,
|
|
neutralized with concentrated HCl, and diluted with 50 mL anhydrous
|
|
Et2O. There was obtained 0.18 g of 2,5-dimethoxy-4-methylamphetamine
|
|
hydrochloride (DOM) as a white solid with a mp of 187-188 !C.
|
|
|
|
The optical isomers of DOM have been prepared in two ways. The
|
|
racemic base has been resolved as the ortho-nitrotartranilic acid salt
|
|
by recrystallization from EtOH. The (+) acid provides the (+) or RSS
|
|
isomer of DOM preferentially. Also, the above-mentioned
|
|
1-(2,5-dimethoxy-4-methylphenyl)-2-propanone can be reductively
|
|
aminated with optically active alpha-methyl benzylamine with Raney
|
|
Nickel. This amine is isolated and purified by recrystallization of
|
|
the hydrochloride salt. When optically pure, the benzyl group was
|
|
removed by hydrogenolysis with palladium on carbon. The mp of either
|
|
of the optical isomers, as the hydrochloride salts, was 204-205 !C.
|
|
|
|
DOSAGE: 3 - 10 mg.
|
|
|
|
DURATION: 14 - 20 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 1.0 mg) There is almost certainly an
|
|
effect. Physically there is a slight dryness in the mouth, and my
|
|
eyes are noticeably dilated. There is an eerie feeling overall.
|
|
|
|
(with 2.3 mg) Mood elevation at 2-3 hrs. After 3 hours, emotional
|
|
effects become more pronounced, enhancement of color also. Very
|
|
little distortion of perception, no disorientation, no creeping or
|
|
flowing, but color enhancement considerable. The emotional content
|
|
and empathy for others was closer to mescaline than to amphetamine, a
|
|
welcome change. No suggestion of nausea at any time. Unable to sleep
|
|
at ten hours, so I took 3/4 grain Seconal. Headache and listlessness
|
|
next morning, probably due to the Seconal.
|
|
|
|
(with 3 mg) In the middle of the experience I found that I was able
|
|
to separate components of complex things so as to evaluate them
|
|
separately. There is no need to respect their normal purpose. The
|
|
sharpness of observation is enhanced, but one can focus at every
|
|
different depth of a thing or a concept. Colors are not just
|
|
brighter; there are more of them. There is a profoundness of meaning
|
|
inherent in anything that moves. A line of thought or a bit of
|
|
personal history ties the thinker to the objects that had been thought
|
|
of, or once experienced. It is this relationship that will prove
|
|
productive. Not like in a movie which is circular in its totalness,
|
|
but as in true life where the future is the result of your own
|
|
involvement with everything about you.
|
|
|
|
(with 4 mg) The first four hours were largely directed to the body.
|
|
There was a shuddering, and a tight jaw, and I am not particularly
|
|
motivated to talk to anyone. It is more arousing (like amphetamine)
|
|
than depressing (like phenobarb). I am feeling just a little sick at
|
|
the three hour point, but a bit of regurgitation clears this up. Then
|
|
at the fourth hour, it went totally outside of me. I saw the clouds
|
|
towards the west. THE CLOUDS!!! No visual experience has ever been
|
|
like this. The meaning of color has just changed completely, there
|
|
are pulsations, and pastels are extremely pastel. And now the oranges
|
|
are coming into play. It is a beautiful experience. Of all past joys,
|
|
LSD, mescaline, cannabis, peyote, this ranks number one. Normally I
|
|
have no color effects with mescaline. A dynamic experience. Feels
|
|
good, too.
|
|
|
|
(with 5 mg) There was the magnification of light, color and odors.
|
|
It was all very pleasant and beautiful, except that I had an
|
|
overwhelmingly negative feeling. This at times grew to considerable
|
|
intensity, and I feel it was clearly due to anger. At times the
|
|
negativity disappeared completely, and I broke into the most
|
|
enjoyable, even hilarious experiences. I alternated about 50-50
|
|
between joy and discomfort. As the evening drew on, I became
|
|
withdrawn and pensive. It seemed clear that I had made all the wrong
|
|
decisions Q choice of partner, place to live, isolation, no meaningful
|
|
activity. The greatest shocker was that my practice of meditation,
|
|
which is one of my central focuses, and which I thought had brought me
|
|
much peace and understanding, seemed to be a delusional solution to my
|
|
unhappiness and isolation. The experience continued unabated
|
|
throughout the night with much tension and discomfort. I was unable
|
|
to get any sleep. I hallucinated quite freely during the night, but
|
|
could stop them at will. While I never felt threatened, I felt I knew
|
|
what it was like to look across the brink to insanity.
|
|
|
|
(with 8 mg) The very quiet development picks up speed betweeen the
|
|
first and second hour. There is a rich curly-imaged eyes-closed show
|
|
that interlocks closely with music. It is occasionally an off-beat
|
|
fantasy and not directly knit together, and even occasionally
|
|
unenjoyable. But always intense and completely appropriate to the
|
|
music. There is a continuous thirst, and little urine. Napping seems
|
|
OK at 16 hours, but real sleep must wait until the 20 hour point.
|
|
Overall a rolling +++, and I am looking forward to a repeat some day.
|
|
|
|
(with 10 mg) If on this page I shall have expressed it to you then it
|
|
is true that DOM has the glory and the doom sealed up in it. All
|
|
that's needed to unseal it is to surround it with a warm living human
|
|
for a few hours. For that human for those hours all the dark things
|
|
are made clear.
|
|
|
|
(with 12 mg) The first awareness was at 30 minutes and it was in the
|
|
tummy. The development was extremely rapid, something more like LSD
|
|
than previously remembered. The body tremor feels like poisoning,
|
|
there is no escaping the feeling of being disabilitated, but at least
|
|
there is no nausea. This transition ended and the trauma cleared
|
|
completely at about the second hour. The music was exceptional, the
|
|
erotic was exceptional, the fantasy was exceptional. Listz's RA
|
|
Christmas Cantata #1,S part 1, with eyes closed was an experience
|
|
without precedent. There were some residual effects still noted the
|
|
next day. This may be a bit much for me.
|
|
|
|
(with 0.3 mg of the RRS isomer) Maybe slightly wiry? No effects.
|
|
|
|
(with 0.5 mg of the RRS isomer) There is a real effect, and it is
|
|
significant that the first effects of the racemate were noted at 1.0
|
|
milligram. There is a trace of time slowing and in general a pretty
|
|
full manic state. There is some mydriasis. Everything had pretty
|
|
much cleared up by evening.
|
|
|
|
(with 2.0 mg of theSSS isomer) No effects. There was an unexpected
|
|
slight tachycardia at the two hour point, but nothing suggesting
|
|
psychotropic action.
|
|
|
|
(with 2.6 mg of the RSS isomer) There are signs of both pulse
|
|
increase and blood pressure increase. There is some teeth-rubbiness,
|
|
but still no psychological turn on at all.
|
|
|
|
EXTENSIONS AND COMMENTARY: The rationale for the design and making of
|
|
DOM has already been discussed. One could predict that it could have
|
|
been, theoretically, a totally inactive compound and maybe an
|
|
effective blocker for whatever receptor sites are being occupied by
|
|
other psychoactive drugs and even for strange things that some
|
|
unbalanced people might actually make within their bodies, using their
|
|
own personal chemistry. On the other hand, it could have been a
|
|
potent psychedelic in its own rights, and if so, probably long lived.
|
|
The latter Rcould have beenS proved to be so.
|
|
|
|
The very modest amount of study of the individual optical isomers
|
|
clearly indicates that the RRS isomer is the more active. The sparse
|
|
comments suggest that some of the heavier physical aspects of the
|
|
racemate might be due to contributions from the RinactiveS RSS isomer.
|
|
It is, after all, the RSS isomer of amphetamine that carries the major
|
|
punch of that stimulant. Maybe if that isomer were removed, and one
|
|
were to explore the pure RRS isomer of DOM, the dramatic visual
|
|
aspects of the larger dosages might not be complicated with a
|
|
troublesome physical component.
|
|
|
|
This compound, unbeknownst to me, was scattered widely and plentifully
|
|
in the heyday of the Haight-Ashbury in San Francisco, in mid-1967. It
|
|
was distributed under the name STP, which was said to stand for
|
|
Serenity, Tranquility, and Peace. It was also claimed to represent
|
|
Super Terrific Psychedelic, or Stop The Police. The police called it:
|
|
Too Stupid to Puke. Actually, the name was taken from the initials of
|
|
a motor additive which was completely unrelated chemically.
|
|
Incredibly, and sadly, one of the avowed experts in the area of the
|
|
Rsensuous drugsS actually stated that STP, the motor oil additive, was
|
|
really one and the same as STP, the highly dangerous psychedelic. The
|
|
motor oil additive, he wrote in a book of his, had properties somewhat
|
|
related to those of LSD, mescaline, and the amphetamines. How
|
|
fortunate that the love children of the time didnUt do much reading,
|
|
for they might have gotten into yet deeper pharmacological troubles
|
|
with drug raids on the local gasoline stations.
|
|
|
|
Two complications became apparent during this first appearance and
|
|
they led to serious difficulties. One, there was no equation made
|
|
between STP and DOM. No one knew what this drug was which had been
|
|
distributed in a cavalier way throughout the city. There could be no
|
|
educated guess as to the best treatment of overdose emergencies. And
|
|
secondly, the initial tablets that had been distributed apparently
|
|
contained 20 milligrams of DOM per tablet; later, it was dropped to 10
|
|
milligrams. Either of these, in retrospect, is now known to be a
|
|
thoroughly whopping dose. The overdose situation was aggravated by
|
|
the slow onset of DOM. The user may be aware of some initial effects
|
|
at the half-hour point, there will be what might be called a + or ++
|
|
at the end of the first hour, and the full impact of the drug is not
|
|
appreciated until some two hours have elapsed. But many of the
|
|
recipients of the free handouts of DOM were familiar with LSD which
|
|
can show its alert in 15 to 20 minutes, or even sooner with a large
|
|
dose, and there is already a deep and compelling intoxication felt at
|
|
the half-hour point. They, quite reasonably, expected this familiar
|
|
activity pattern with STP and assumed, when there was little if any
|
|
activity noted at the half-hour point, that the potency was less than
|
|
expected. They took one or even two additional dosage units. Thus,
|
|
some of the overdose victims of that period may well have taken as
|
|
much as 30 mg of DOM. The slow onset of action, coupled with the
|
|
remarkably long duration, caught many innocent users unprepared.
|
|
|
|
Clinical studies have documented the rapid tolerance development from
|
|
repeated exposures to DOM. Five volunteers were given 6 milligrams
|
|
daily for three days. Objectively, psychological tests showed a
|
|
decrease in responses. Subjectively, all found extremely intense
|
|
effects on the first day, and all but one found it unpleasant. By the
|
|
third exposure on the third day, all had diminished responses, ranging
|
|
from only Rmoderately strongS to Rfelt absolutely nothing.S One
|
|
actually slept during the experience on the third day.
|
|
|
|
The hexadeutero-analogue (deuterium atoms on the two methoxyl groups)
|
|
has been prepared as an internal standard for analytical work, but
|
|
there are no reports of its human pharmacology. A study with this
|
|
sort of derivative would be a fine companion to the studies already
|
|
underway with the mescaline analogues that are similarly substituted.
|
|
A difference exists, however. With mescaline, it is believed that the
|
|
loss of a methoxyl group is a step towards the inactivation of the
|
|
compound, whereas with DOM this loss may be associated with the
|
|
formation of an active metabolite. The several fascinating questions
|
|
raised by possible differences in both the rates and the degree of
|
|
demethylation of these two compounds are well worth trying to answer.
|
|
|
|
A number of compounds related to DOM had been synthesized and studied
|
|
at the University of California at San Francisco, at about this time.
|
|
Two of these were simply the juggling of the two methoxyl groups and
|
|
the methyl group on the ring, still maintaining the 2,4,5-ness
|
|
relative to the amphetamine chain. These are
|
|
2,4-dimethoxy-5-methylamphetamine and
|
|
4,5-dimethoxy-2-methylamphetamine. Since the slang name for DOM in
|
|
and about the medical center was STP, and since STP was the name of a
|
|
motor oil additive, it is not unreasonable that the first of these to
|
|
be synthesized, the 2,4-dimethoxy-5-methyl isomer, was referred to by
|
|
the name of another motor oil additive popular at that time, F-310.
|
|
The Vilsmeier reaction between 2,4-dimethoxytoluene and the Vilsmeier
|
|
complex of POCl3 and N-methylformanilide gave the benzaldehyde (mp
|
|
117-118 !C) with a yellow malononitrile derivative from EtOH with a mp
|
|
of 193-194 !C. The nitrostyrene from this and nitroethane formed
|
|
yellow crystals from CH3CN, with a mp 138-139 !C. The amine formed
|
|
easily with LAH in ether, and the product F-310 (or 5-DOM) gave white
|
|
crystals from CH3CN with a mp of 182-183 !C.
|
|
|
|
And the other isomer, the 4,5-dimethoxy-2-methyl counterpart, became
|
|
known familiarly as F-320, or sometimes simply 2-DOM. Its preparation
|
|
followed an identical procedure, starting from 3,4-dimethoxytoluene.
|
|
I have been told that F-310 is not active even at 20 milligrams in
|
|
man, which would make it several times less potent than DOM (STP). I
|
|
know of no trials with F-320. The use of the letter RFS does not
|
|
imply any relationship between these two compounds and the series
|
|
described elsewhere with the RFS code followed by other numbers, such
|
|
as F-2 and F-22. These latter are F's because they are furans, not
|
|
motor oil additives. And yet another oil additive, well known at the
|
|
time as Z-7, became associated with the synthesis of the DOM (STP)
|
|
isomer with its groups in the 2,4,6-positions. This is entered
|
|
separately under y-DOM.

#69 Y-DOM; Z-7; 2,6-DIMETHOXY-4-METHYLAMPHETAMINE
|
|
|
|
SYNTHESIS: To a solution of 2,6-dimethoxy-4-methylbenzaldehyde (mp
|
|
92-93 !C from the lithiation of 3,5-dimethoxytoluene followed by
|
|
reaction with N-methylformanilide) in 10 mL nitroethane, there was
|
|
added 0.1 g anhydrous am-monium acetate and the mixture was heated on
|
|
the steam bath for 16 h. Removal of the solvent under vacuum gave a
|
|
slightly oily red-orange crystalline mass which was finely ground
|
|
under 1 mL of MeOH. Filtration and a sparing wash with MeOH gave,
|
|
after air drying, 0.8 g of a light yellow crystalline solid with a mp
|
|
of 121-122.5 !C. Recrystallization from 4 mL boiling absolute EtOH
|
|
gave 0.6 g of 1-(2,6-dimethoxy-4-methylphenyl)-2-nitropropene as very
|
|
light yellow platelets, which melted at 123-124 !C.
|
|
|
|
To a solution of 0.25 g LAH in 25 mL refluxing THF, well stirred and
|
|
under He, there was added a solution of 0.3 g
|
|
1-(2,6-dimethoxy-4-methylphenyl)-2-nitropropene in 5 mL dry THF. Upon
|
|
the completion of the addition, the reaction mixture was held at
|
|
reflux for 48 h. After cooling with an external ice bath there was
|
|
added, in sequence, 0.5 mL H2O, 0.5 mL 15% NaOH, and finally 1.5 mL
|
|
H2O. The inorganic solids were removed by filtration, and the filter
|
|
cake washed with THF. The solvent from the combined filtrate and
|
|
washings was removed under vacuum, and the residue (0.3 g) was a
|
|
crystal clear colorless oil with a high refractive index. This was
|
|
dissolved in 2 mL IPA, neutralized with concentrated HCl, and diluted
|
|
with 35 mL of anhydrous Et2O. After a minute's standing, the solution
|
|
became turbid, followed by the slow deposition of very fine white
|
|
crystals. After standing 1 h at room temperature, these were removed
|
|
by filtration, Et2O washed, and air dried to constant weight. There
|
|
was thus obtained 0.3 g 2,6-dimethoxy-4-methylamphetamine
|
|
hydrochloride (y-DOM) with a mp of 203 !C. sharp.
|
|
|
|
DOSAGE: 15 - 25 mg.
|
|
|
|
DURATION: 6 - 8 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 14 mg) I am really quite spacey. I can
|
|
go from a train of thought straight up into thin air. Then, to get to
|
|
another one there must be a careful choice of words. Logic has
|
|
nothing to do with any of it. There is no trace of the MDMA-like
|
|
magic. This is an interpretive drug, not simply an ASC [altered state
|
|
of consciousness] opening.
|
|
|
|
(with 18 mg) There is a light-headedness, and a somewhat starry-eyed
|
|
stoned state. Nothing visual, and no body concern except for what
|
|
seems to be a very fine inner tremor. I think that with a little
|
|
more, things might very well begin to move in the visual field. But I
|
|
have no feeling of great concern about taking a somewhat higher
|
|
dosage.
|
|
|
|
(with 25 mg) I was at a +++ for about three hours, and it was a very
|
|
weird place. There were some visuals, but they were not at all
|
|
commensurate with the degree to which I was simply stoned. The erotic
|
|
does not knit, and it's hard to get involved with music. It is as if
|
|
you were going down some totally unknown street in a completely
|
|
familiar city. You know the territory, but yet it is strangely all
|
|
new. Eyes closed fantasy and shaped imagery was quite remarkable.
|
|
But some heart arrhythmias and a pretty constant diarrhea made the
|
|
experience less than totally ideal. My sleep was good and with good
|
|
dreams.
|
|
|
|
EXTENSIONS AND COMMENTARY: I canUt remember the exact names of the
|
|
companies that went with the oil additives. STP was, I believe, itUs
|
|
own thing, and originally stood for Scientifically Treated Petroleum.
|
|
And F-310 was, I believe, a Chevron Oil product. F-320 was, of
|
|
course, the product of the wild and happy chemists at the
|
|
Pharmaceutical Chemistry Department at the University of California in
|
|
San Francisco, playing with what they fondly called Rfunny drugs.S And
|
|
when the 2,4,6-orientation became an obvious positional isomer, the
|
|
Pennzoil Oil Company's additive, Z-7, was a natural to have its name
|
|
volunteered to the cause. There was one additional isomer possible,
|
|
with the methyl in the 2-position and the methoxyl groups at the 4-
|
|
and 6-positions. This followed the more conventional aldehyde made
|
|
from 3,5-dimethoxytoluene via the Vilsmeier process, with POCl3 and
|
|
N-methylformanilide. This material
|
|
(2,4-dimethoxy-6-methylbenzaldehyde with mp 64-65 !C from cyclohexane
|
|
or from MeOH) is completely distinct from the isomer used above
|
|
(2,6-dimethoxy-4-methylbenzaldehyde with a mp of 92-93 !C from MeOH).
|
|
The amphetamine from this isomer is 2,4-dimethoxy-6-methylamphetamine,
|
|
and had been christened by the chemistry crowd as Z-7.1.
|
|
|
|
Much effort had been put forth in research by this medical school
|
|
group of graduate students and graduate advisors, to try to explain
|
|
the biological activity of the 2,4,5-things such as TMA-2 and DOM
|
|
(STP). And a considerable investment had been made in the attempt to
|
|
tie together the amphetamine world of psychedelics with the indole
|
|
world of psychedelics. The convenience of having two methoxy groups
|
|
para to one another was a clear invitation to speculate upon the
|
|
formation of a benzoquinone intermediate of some kind, and this would
|
|
require the loss of the methyl groups which were already known to be
|
|
metabolically labile. This Rquinone-likeS intermediate was the
|
|
cornerstone of a Rhydroquinone hypothesis,S as it allowed further
|
|
condensation within the molecule itself involving the primary amine
|
|
group, to form something called an indolene which, with some arcane
|
|
electron pushing and removal, could eventually become an indole.
|
|
There. We now have a tie-in to the tryptamine world, and to
|
|
serotonin, and that entire neurotransmitter magic.
|
|
|
|
There was only one small fly in the ointment. No matter how the
|
|
2,4,5-things were explained, none of the proposed mechanisms could
|
|
allow for the 2,4,6-things to also be active.
|
|
|
|
How can one accommodate such blasphemy? The first and obvious
|
|
approach was the simplest. Denial. The 2,4,6-things arenUt really
|
|
active at all. Placebo stuff. There is a commonly used phrase, Rbad
|
|
scienceS which is an in-famous term used to belittle findings that do
|
|
not fit with one's theories or purposes. But that simply didnUt wash,
|
|
because I knew, as did a few others who chose not to identify
|
|
themselves too publicly, that TMA-2 and TMA-6 were both fully active
|
|
in the 40 to 50 milligram area. And although not as potent as DOM,
|
|
the compound of this recipe, y-DOM or Z-7, was certainly an active
|
|
one. So, since approach number one didnUt work, try approach number
|
|
two. Make the shoe fit the wearer, without respect to the size of his
|
|
foot. One single size shoe fits all. One single mechanistic
|
|
hypothesis explains all. It was obvious that for the RhydroquinoneS
|
|
hypothesis to survive, Z-7 would have to undergo some metabolic
|
|
oxidation Q phenol formation Q in the 3-position.
|
|
|
|
And guess who was actually euchred into embarking onto the synthesis
|
|
of this hypothetical metabolic Lucy [that's the anthropological-type,
|
|
not the LSD-type Lucy]? Moi! On to a new methoxylated amphetamine
|
|
which would be called Z-7.2. Oxidation of the above
|
|
2,4-dimethoxy-6-methylbenzaldehyde with metachloroperoxybenzoic acid
|
|
gave 2,4-dimethoxy-6-methylphenol which smoothly methylated (KOH,
|
|
CH3I) to give 2,3,5-trimethoxytoluene as a white oil, bp 59-62 !C at
|
|
0.1 mm/Hg. This formed the anion between the meta-methoxy groups with
|
|
butyllithium, and N-methylformanilide gave the new compound
|
|
2,3,6-trimethoxy-4-methylbenzaldehyde, also an oil (bp 130-140 !C at
|
|
0.7 mm/Hg) with an excellent NMR spectrum. This formed the 3-carbon
|
|
nitrostyrene with nitroethane, as bright yellow crystals from methanol
|
|
with a mp 67-68.5 !C (and excellent NMR and microanalysis, C,H,N).
|
|
Lithium aluminum hydride reduction gave rise to what I was assuming
|
|
would be the target amphetamine, 4-methyl-2,3,6-trimethoxyamphetamine
|
|
or Z-7.2. This formed a hydrochloride salt which, although
|
|
analytically excellent, insisted in remaining as an ether and
|
|
chloroform-soluble oil which had an excellent NMR spectrum. This was
|
|
certainly MY target compound, but it was not THEIR target compound.
|
|
The upper echelons who were running the show were serious about this
|
|
hydroquinone thing. Therefore, this product Z-7.2, that should have
|
|
been entered into human evaluation, was instead processed further by
|
|
the substitution of a t-BOC on the amine group, oxidation to the
|
|
quinone with ceric ammonium nitrate, reduction to the hydroquinone
|
|
with dithionite, and finally deprotection of the blocking t-BOC group
|
|
by hydrochloric acid. The final product,
|
|
2,5-dihydroxy-6-methoxy-4-methylamphetamine hydrochloride, was an
|
|
extremely light-sensitive solid which was looked at by NMR (excellent
|
|
spectrum in D2O) and by cyclic voltimetry (destructive and
|
|
uninformative) but which would have been totally worthless to have
|
|
tasted.
|
|
|
|
In fact, the whole 2,4,6 substitution concept is just now beginning to
|
|
explode. Fully half of the drugs described in this Book II are of the
|
|
classical 2,4,5-trisubstitution pattern, and it is becoming evident
|
|
that every one of them will have a 2,4,6-trisubstituted counterpart
|
|
that bids fair to be an active psychedelic. Diligence could thus
|
|
easily double the number of known psychedelics. The nickname RpseudoS
|
|
is really the Greek letter RpsiS which looks like a candelabrum
|
|
standing on the table holding up three candles. If I can find the
|
|
type in some font, I will simply precede each known drug with this
|
|
letter, to indicate that the 2,4,5-ness has become a 2,4,6-ness.
|
|
Therefore, Z-7 is also pseudo-DOM.
|
|
|
|
Z-7.2 might have been an interesting compound to taste. But the
|
|
academic climate was not appropriate at that time (early 1977) for
|
|
such honesty. The Rhydro-quinone hypothesisS is now not much more
|
|
than a minor bit of history. And anyhow, it was just about this time
|
|
that I had uncovered a slick way of getting a sulfur atom into the
|
|
amphetamine molecule. I quickly lost interest in the pursuit of other
|
|
people's hypotheses that didnUt seem to lead anywhere. Maybe,
|
|
someday, some single earth-shaking mechanism will emerge to explain
|
|
everything. But in the meantime, the best contribution I can make to
|
|
this Rgrand unified theory of psychedelic activityS is to continue to
|
|
make new and unexpected things which, if they are active, will
|
|
effectively destroy any hypothesis that just happens to be popular at
|
|
the moment. It is a lot more exciting, too.

#70 DON; 2,5-DIMETHOXY-4-NITROAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 8.4 g 2,5-dimethoxyamphetamine base in 40 mL
|
|
acetic acid was added dropwise over the course of 0.5 h to 43 mL of
|
|
50% nitric acid which was well stirred and cooled with an external ice
|
|
bath. The resulting solution was quenched with ice water, made basic
|
|
with aqueous NaOH, and extracted with a benzene-ether mixture. The
|
|
residue that remained after the removal of the solvent was dissolved
|
|
in dilute HCl which, upon evaporation of the H2O, yielded a nearly
|
|
colorless residue. Recrystallization from an ethanol/ether mixture
|
|
gave, after drying, 10.5 g of 2,5-dimethoxy-4-nitroamphetamine
|
|
hydrochloride (DON) with a mp of 206-207 !C. The acetamide derivative
|
|
melted at 166-168 !C. The formamide derivative was easily hydrolyzed
|
|
with 3N HCl. And the R-isomer of DON hydrochloride had a mp of
|
|
231-232 !C.
|
|
|
|
DOSAGE: 3.0 - 4.5 mg.
|
|
|
|
DURATION: 8 - 15 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 3.0 mg) There was an amphetamine-like
|
|
stimulation that was apparent an hour into it, and considerable
|
|
anxiety. I had stomach cramps, but there were indications that there
|
|
might be something hallucinogenic at a higher dose.
|
|
|
|
(with 4.5 mg) An enhancement of color perception, and some auditory
|
|
distortion, that was still noticeable some eight hours into the
|
|
experience. The visual changes were intense. I felt I was running a
|
|
slight fever, and was restless, but there was almost no physical
|
|
malaise. I was still somewhat wound up even at the 14th hour.
|
|
|
|
EXTENSIONS AND COMMENTARY: These qualitative comments are not true
|
|
quotations, but have been reconstructed from the published summaries
|
|
of the human trials reported by several South American researchers. I
|
|
have personally never tasted DON and have only these fragments from
|
|
which to create a portrait of activity. A brief quotation, from a
|
|
note published by these researchers in a bulletin that is restricted
|
|
to forensic scientists serving law enforcement agencies, is certainly
|
|
subject to a number of interpretations. It reads as follows: RThis
|
|
action [a strong stimulant action reminiscent of amphetamine] seems to
|
|
reduce the incidence of insightful, and therefore potentially
|
|
unpleasant experiences, and thus [DON seems likely] to appear on the
|
|
market as an illicit recreational drug.S I must admit that I have
|
|
tried, and I am still not able, to interpret this quotation.

#71 DOPR; 2,5-DIMETHOXY-4-(n)-PROPYLAMPHETAMINE
|
|
|
|
SYNTHESIS: A suspension of 285 g mossy zinc in 285 mL H2O containing
|
|
5.7 g mercuric chloride was treated with 285 mL concentrated HCl and
|
|
shaken as needed to effect amalgamation. The H2O was then drained
|
|
off, the zinc washed with fresh water and drained again. There was
|
|
added a solution of 74 g 2,5-dimethoxypropiophenone (from the reaction
|
|
of propionic acid and p-dimethoxybenzene in the presence of
|
|
polyphosphoric acid, see under DOAM for an effective general
|
|
procedure) in 140 g EtOH. The reaction mixture was held at reflux for
|
|
24 h with the periodic addition of concentrated HCl. It was then
|
|
cooled, diluted with H2O and CH2Cl2, and the organic phase separated.
|
|
The aqueous phase was extracted with 2x100 mL additional CH2Cl2. The
|
|
combined organic phases were washed with 5% NaOH until the washes
|
|
remained basic, once with H2O, and then the solvent was removed under
|
|
vacuum. The residue was distilled at the water pump, giving an early
|
|
fraction quite rich in starting p-dimethoxybenzene, and a second
|
|
fraction (61 g, bp 140-160 !C) which was free of carbonyl group by
|
|
infra-red, and which was largely 2,5-dimethoxypropylbenzene. It was
|
|
used without further purification in the following aldehyde synthetic
|
|
step.
|
|
|
|
A mixture of 124 g N-methylformanilide and 140 g POCl3 was allowed to
|
|
stand until there was the development of a strong red color. There
|
|
was then added 60 g of the above 2,5-dimethoxypropylbenzene and the
|
|
mixture was held on the steam bath for 2 h. The mixture was added to
|
|
2 L H2O and stirred until the excess acid chloride had completely
|
|
decomposed. The mixture was extracted with 3x100 mL CH2Cl2 and, after
|
|
the removal of the solvent from the combined extracts, the residue was
|
|
extracted with 3x100 mL boiling hexane. Removal of the solvent gave
|
|
the product 2,5-dimethoxy-4-propylbenzaldehyde as an oil, 23 g, which
|
|
was characterized as its malononitrile derivative. Equal weights of
|
|
the product and malononitrile in EtOH with a catalytic amount of
|
|
triethylamine gave yellow crystals which, on recrystallization from
|
|
toluene, had a mp of 113-114 !C.
|
|
|
|
A solution of 21.5 g of the above crude
|
|
2,5-dimethoxy-4-propylbenzaldehyde in 75 g acetic acid, was treated
|
|
with 10.4 g nitroethane and 6.6 g anhydrous ammonium acetate. This
|
|
was heated on the steam bath for 1.75 h, then cooled and diluted with
|
|
H2O to the point of turbidity. With long standing and scratching,
|
|
there finally was the deposition of crystals which were removed by
|
|
filtration and sucked as dry as possible. This 23 g of crude product
|
|
cake was triturated under MeOH, filtered again, and air dried to give
|
|
11 g of dull orange crystals. Recrystallization from boiling MeOH
|
|
gave 1-(2,5-dimethoxy-4-(n)-propylphenyl)-2-nitropropene as fine
|
|
orange crystals which weighed, after filtering, washing, and drying,
|
|
7.4 g, and which had a mp of 94-96 !C.
|
|
|
|
To a suspension of 6.0 g LAH in 500 mL anhydrous Et2O, which was being
|
|
stirred and also held as a gentle reflux, there was added a saturated
|
|
solution of (2,5-dimethoxy-4-(n)-propylphenyl)-2-nitropropene in warm
|
|
THF. The reaction mixture was held at reflux for 24 h, then cooled to
|
|
room temperature. The excess hydride was destroyed by the cautious
|
|
addition of 500 mL dilute H2SO4. The phases were separated, and the
|
|
aqueous phase washed with additional Et2O. There was then added 150 g
|
|
potassium sodium tartrate, and the pH was brought to >9 with aqueous
|
|
NaOH. The product was extracted with Et2O and, after removal of the
|
|
solvent, the residue was dissolved in 200 mL anhydrous Et2O and
|
|
saturated with anhydrous HCl gas. The solids that formed were removed
|
|
by filtration, giving 6.15 g 2,5-dimethoxy-4-(n)-propylamphetamine
|
|
hydrochloride (DOPR) as an electrostatic, white crystalline powder,
|
|
with a mp of 182.5-183 !C. This was not improved by recrystallization
|
|
from either IPA or CH3CN.
|
|
|
|
DOSAGE: 2.5 - 5.0 mg.
|
|
|
|
DURATION: 20 - 30 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 2.0 mg) The onset is slower than any
|
|
other thing I can think of. There was nothing at all at the end of an
|
|
hour, and only a threshold a half hour later. By the middle of the
|
|
third hour, I was up to 1+, and that seemed to be about as high as it
|
|
intended to take me. Attempts to sleep at the ninth hour were not
|
|
successful, as there were strange patterns of not-quite logical
|
|
thinking going on. Stuff like: TThe block events (like a babyUs
|
|
rectangular building blocks) that were gotten, along with other
|
|
things, from the full octaves of the left hand in Listz's Hungarian
|
|
Rhapsody, events that allowed an easy recognition of the odds of
|
|
achieving successful re-entry from any of several erotic codes.U
|
|
Clearly this was not a baseline state. After six hours of successful
|
|
sleep, I was still off-baseline , and on into the following day. Go
|
|
on up with curiosity but with caution.
|
|
|
|
(with 3.6 mg) Imagery that was constructed in response to the music
|
|
turned out to be necessary to organize and contain it. The trio is the
|
|
nucleus that transforms the written to the heard, but it has created
|
|
its own bubble without connections to the real world, and must play on
|
|
and on and on to keep itself afloat and never touching the stage
|
|
again.
|
|
|
|
(with 5.0 mg) I am now at midnight, and still strongly +++. This is
|
|
certainly maximum dosage, at least for a long time. There are faint
|
|
intimations of nervous system scrungies. You know, the kind of thing
|
|
that makes you figure it's going to be a while before youUll try to
|
|
relax into sleep. This material, like all the other DOUs, is a heavy
|
|
duty psychedelic, the kind that says to you, 'Forget all that stuff
|
|
about screening out visuals,' and then proceeds to prove it. Sort of
|
|
indole-like in that way. Your body as well as your mind tells you
|
|
youUre into it, baby, and better relax and enjoy the trip, because
|
|
youUve left the shore way behind. When it was time for bed, I got to
|
|
sleep with surprising ease, and slept for only about six hours. My
|
|
dreams were excellent, balancing, and good humored. But the next day
|
|
I realized I was still carrying the DOPR in me, and that baseline was
|
|
definitely not there. But it was OK. No problems except for
|
|
sleepiness. The next evening I went to bed at unheard-of hour of 9 PM
|
|
and slept for 13 hours, give or take. Fascinating compound, but I
|
|
wonUt go out of my way to take it again soon.
|
|
|
|
EXTENSIONS AND COMMENTARY: There is a thread of disconnection and of
|
|
inconsistent reference that pervades most of the reports that I have
|
|
received concerning the use of DOPR. The word that comes to mind is
|
|
hypnogogic. There is a drifting into that place that lies between a
|
|
not-quite-awake and a not-quite-asleep state seems to characterize
|
|
this compound. There is no question but that it is very potent, and
|
|
that it is very long-lived. But there is a nagging suggestion of the
|
|
out-of-body, out-of-center character that is the hallmark of the
|
|
anesthetic and delusional drugs such as scopolamine or ketamine. With
|
|
them, the psychedelic effects become clouded with touches of amnesia.
|
|
If DOPR shows this with it's three carbon alkyl group, thereis every
|
|
reason to pay close attention as the chain becomes longer.
|
|
|
|
There had been quite a bit of speculation in the literature that the
|
|
metabolic attack on DOM was at the 4-position, and this was an
|
|
oxidation process. In a moment of inspiration, I decided to explore a
|
|
similar oxidation step in DOPR, since it is probably the most potent
|
|
of the DO-series. Why not make the compound which would be the first
|
|
step in this oxidation, the 1-hydroxypropyl analogue? This I did, by
|
|
using the phthalimide derivative of 2,5-dimethoxyamphetamine
|
|
(described in the synthesis of DOI) and making the propiophenone using
|
|
propionic acid as both reagent and solvent, and polyphosphoric acid as
|
|
the condensing agent. The ketone product (a white crystalline solid
|
|
from methanol) was dissolved in warm methanol and reduced to the
|
|
alcohol with sodium borohydride. This product, also a white
|
|
crystalline solid, was stripped of the phthalimide blocking group with
|
|
overnight refluxing with hydrazine in ethanol. The product,
|
|
2,5-dimethoxy-4-(1-hydroxypropyl)-amphetamine (hydroxy-DOPR) had a mp
|
|
of 148-150 !C from IPA. Its activity is not yet known, but there were
|
|
no effects at all at trials, orally, of up to 200 micrograms.
|
|
|
|
But this is all with the normal-propyl compound. There is a rich
|
|
collection of misinformation and potential discovery that is
|
|
associated with the isopropyl isomer. This structural isomer,
|
|
2,5-dimethoxyl-4-(i)-propylamphetamine is properly called DOIP for
|
|
des-oxy-iso-propyl. It has been synthesized and explored in animals
|
|
and, to a modest extent, in man. The synthesis has proceeded from
|
|
2,5-dimethoxyacetophenone by the addition of a methyl group to the
|
|
carbonyl followed by reduction to the hydrocarbon. Aldehyde
|
|
formation, nitropropene synthesis with nitroethane, and lithium
|
|
aluminum hydride reduction are uneventful, providing the hydrochloride
|
|
salt DOIP, which has a mp of 183-184 !C as an analytical sample.
|
|
Animal tests (such as rabbit hyperthermia assays), have indicated that
|
|
the isopropyl compound DOIP is less potent than the propyl prototype,
|
|
DOPR, by between one and two orders of magnitude. In man, a dose of
|
|
four milligrams, a rousing dose of DOPR, is without any effects. At
|
|
10 milligrams, there is some disturbance but substantially no effects.
|
|
I have been told that with doses in the 20 to 30 milligram range there
|
|
are valid changes in mental state, but I have not been told the nature
|
|
of these changes.
|
|
|
|
A fascinating red herring had been drawn across all of these exacting
|
|
lines by a strange visitor to this research project. An olive-faced
|
|
M.D., Ph.D., passed through this confusing scene briefly, and when he
|
|
left, a small supply of DOPR left with him. He promptly published in
|
|
an obscure journal some animal behavioral responses which he ascribed
|
|
to the isopropyl analogue, DOIP. But what he had studied could only
|
|
have been DOPR since DOIP, at that time, had not yet been synthesized
|
|
either by me, or by either of the other two active synthesists of that
|
|
moment. It was not yet a known material. We all made it some time
|
|
later, but by that time our olive-face had disappeared. There is a
|
|
magnificent French phrase that applies here as nowhere else; Il a
|
|
foutu le camp. Its idiomatic meaning is equivalent to our, RHe took
|
|
off,S or RHe split the scene,S but the literal translation is, RHe
|
|
fucked the camp.

#72 E; ESCALINE; 3,5-DIMETHOXY-4-ETHOXYPHENETHYLAMINE
|
|
|
|
SYNTHESIS: To a solution of 72.3 g 2,6-dimethoxyphenol in 400 mL MeOH,
|
|
there was added 53.3 g of a 40% solution of aqueous dimethylamine
|
|
folowed by 40 g of a 40% aqueous solution of formaldehyde. The dark
|
|
solution was heated under reflux for 1.5 h on a steambath. The
|
|
volatiles were then removed under vacuum yielding a dark oily residue
|
|
of 2,6-dimethoxy-4-dimethylaminomethylphenol. This residue was
|
|
dissolved in 400 mL of IPA, to which there was added 50 mL of methyl
|
|
iodide. The spontaneously exothermic reaction deposited crystals
|
|
within 3 min, and was allowed to return to room temperature and
|
|
occasionally stirred over the course of 4 h. The solids were removed
|
|
by filtration, washed with cold IPA, and allowed to air dry yielding
|
|
160 g of the methiodide of 2,6-dimethoxy-4-dimethylaminomethylphenol
|
|
as a cream-colored crystalline solid.
|
|
|
|
A suspension of 155 g of the above methiodide of
|
|
2,6-dimethoxy-4-dimethylaminophenol in 600 mL H2O was treated with a
|
|
solution of 130 g KCN in 300 mL H2O. The reaction mixture was heated
|
|
on a steam bath for 6 h during which time there was a complete
|
|
dissolving, the development of a brownish color with a bright blue
|
|
film on the surface and the walls of the flask, and the gentle
|
|
evolution of fine gas bubbles. The hot reaction mixture was poured
|
|
into 1.2 L H2O and acidified with concentrated HCl (careful, HCN
|
|
evolution). The aqueous solution was extracted with 3x150 mL CH2Cl2,
|
|
the extracts pooled, washed with saturated NaHCO3 which removed much
|
|
of the color. The solvent was removed under vacuum yielding about 70
|
|
g of a viscous black oil. This was distilled at 0.4 mm/Hg at 150-160
|
|
!C to provide 52.4 g of homosyringonitrile
|
|
(3,5-dimethoxy-4-hydroxyphenylacetonitrile) as a white oil that
|
|
spontaneously crystallized to lustrous white crystals that melted at
|
|
57-58 !C.
|
|
|
|
A solution of 5.75 g of homosyringonitrile and 12.1 g ethyl iodide in
|
|
50 mL dry acetone was treated with 6.9 g finely powdered anhydrous
|
|
K2CO3 and held at reflux for 18 h. The mixture was diluted with 100
|
|
mL Et2O, filtered, and the filtrate solvent removed under vacuum The
|
|
residue was recrystallized from Et2O/hexane to yield 5.7 g
|
|
3,5-dimethoxy-4-ethoxyphenylacetonitrile with a mp 57-58 !C. Anal.
|
|
(C12H15NO3) C,H,N.
|
|
|
|
A solution of 2.21 g 3,5-dimethoxy-4-ethoxyphenylacetonitrile in 25 mL
|
|
EtOH containing 2.5 mL concentrated HCl and 400 mg 10% palladium on
|
|
charcoal, was shaken in a 50 lb/sq.in. atmosphere of hydrogen for 24
|
|
h. Celite was added to the reaction suspension and, following
|
|
filtration, the solvents were removed under vacuum. The residue was
|
|
recrystallized from IPA/Et2O to yield 2.14 g
|
|
3,5-dimethoxy-4-ethoxyphenethylamine hydrochloride (E) with a mp of
|
|
166-167 !C.
|
|
|
|
Synthesis from syringaldehyde: A well-stirred suspension of 21.9 g
|
|
syringaldehyde in 45 mL H2O was heated to reflux in a heating mantle.
|
|
There was then added a solution of 15 g NaOH in 60 mL H2O. The
|
|
heating and stirring was continued until the generated solids
|
|
redissolved. Over a period of 10 min, there was added 23 g diethyl
|
|
sulfate, then refluxing was continued for 1 h. Four additional
|
|
portions each of 5 g diethyl sulfate and of 6 mL 20% NaOH were
|
|
alternately added to the boiling solution over the course of 2 h. The
|
|
cooled reaction mixture was extracted with Et2O, the extracts pooled
|
|
and dried over anhydrous MgSO4, decolorized with Norite, and stripped
|
|
of solvent. The crude 3,5-dimethoxy-4-ethoxy-benzaldehyde weighed
|
|
21.8 g and melted at 51-52 !C.
|
|
|
|
A solution of 14.7 g 3,5-dimethoxy-4-ethoxybenzaldehyde and 7.2 mL
|
|
nitromethane in 50 mL glacial acetic acid was treated with 4.4 g
|
|
anhydrous am-monium acetate and held at reflux for 30 min. Cooling
|
|
the reaction allowed the formation of yellow crystals which were
|
|
removed by filtration and washed sparingly with cold acetic acid. The
|
|
dried 3,5-dimethoxy-4-ethoxy-'-nitrostyrene weighed 11.5 g and melted
|
|
at 108-109 !C after recrystallization from EtOH Anal. (C12H15NO5) C,H.
|
|
Alternately, this product may be prepared from 3.9 g.
|
|
3,5-dimethoxy-4-ethoxybenzaldehyde in 60 mL nitromethane containing
|
|
0.7 g ammonium acetate and heated on a steam bath for 1 h. The
|
|
solvent was removed under vacuum, and the residue dissolved in a
|
|
minimum of hot MeOH. Cooling provided, after filtration and air
|
|
drying, 2.3 g of bright yellow crystals of
|
|
3,5-dimethoxy-4-ethoxy-'-nitrostyrene, with a mp of 105-107 !C.
|
|
|
|
A solution of 2.25 g LAH in 45 mL anhydrous THF was vigorously stirred
|
|
and cooled to 0 !C under He. There was added 1.5 mL 100% H2SO4
|
|
dropwise, followed by 2.3 g 3,5-dimethoxy-4-ethoxy-'-nitrostyrene in
|
|
anhydrous THF. After the addition was complete, the mixture was
|
|
allowed to stir for 30 min, and then brought to room temperature. The
|
|
unreacted hydride was decomposed with 2.3 mL H2O in THF, followed by
|
|
the addition of 9.2 mL of 15% NaOH. The white suspension was
|
|
filtered, the filter cake was washed with THF, the filtrate and
|
|
washings combined, and the solvent removed under vacuum. The residue
|
|
was dissolved in 300 mL dilute H2SO4, washed with 2x75 mL CH2Cl2, made
|
|
basic with 25% NaOH, and the product extracted with 3x75 mL CH2Cl2.
|
|
After removal of the solvent, the residue was distilled at 110-120 !C
|
|
at 0.3 mm/Hg yielding 1.4 g of a colorless oil. A solution of this
|
|
oil in 20 mL IPA was neutralized with 17 drops of concentrated HCl and
|
|
diluted with 100 mL anhydrous Et2O. After a few minutes there was the
|
|
spontaneous formation of white crystals of
|
|
3,5-dimethoxy-4-ethoxyphenethylamine hydrochloride (E) which was
|
|
recrystallized from 40 mL boiling EtOAc containing 1 mL MeOH. The mp
|
|
was 165-166 !C.
|
|
|
|
DOSAGE: 40 - 60 mg.
|
|
|
|
DURATION: 8 - 12 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 40 mg) This is a powerful and complex
|
|
intoxicant Q I could not have coordinated any rational muscular
|
|
activity. I could not walk; I could not tie my shoe-laces. There is
|
|
analgesia and an incoordination that I cannot shake. My menstrual
|
|
flow started a bit ahead of time, but it was light.
|
|
|
|
(with 50 mg) I felt that the body tensions outweighed the
|
|
psychological and sensory rewards, in that I had a lot of dehydration
|
|
and my sleep had a nightmare quality. This pretty much offset the few
|
|
virtues that I felt I had obtained.
|
|
|
|
(with 60 mg) There is a quality of rational analysis and insight that
|
|
is totally impressive. Many subtle factors in my life can be viewed
|
|
with insight, and usefully dissected. I got into a deep discussion,
|
|
but I was not argumentative or even defensive and I remained detached
|
|
and kept a tone of cool impersonality. I had a good appetite. But I
|
|
also had some tachycardia and muscular tension. There was
|
|
unquestionable sensory enhancement, but without an intellectual
|
|
component. Overall it was most pleasant.
|
|
|
|
EXTENSIONS AND COMMENTARY: In an isolated situation, there is easy
|
|
fantasy, but little synthesis of external sensory inputs such as music
|
|
or visual stimulae. A gradual decline brings the subject back to a
|
|
restful baseline somewhere before the 12th hour. The following day is
|
|
often seen as one of tiredness and low energy. An anonymous flyer
|
|
appeared in the California drug community in 1984 stating an effective
|
|
range to be 50 to 100 milligrams, but it described the drug as the
|
|
sulfate. The above data all pertain to the hydrochloride salt.
|
|
|
|
The replacement of that one methyl group with an ethyl group leads to
|
|
a nice jeu de mots. The play on words depends on a remarkable
|
|
coincidence. The name of the alkaloid mescaline stems from an ancient
|
|
Nahuatl word for a drink (Mexcalli) which also provided the source of
|
|
the term Mescal (an Agave of entirely different pharmacology). The
|
|
prefix for the simplest, the one carbon organic radical, is methyl.
|
|
This is from the Greek word RmethyS and represents wine from wood.
|
|
Such is, indeed, methyl alcohol, or methanol, or wood alcohol, the
|
|
simplest one-carbon drink and a rather dangerous one for the human
|
|
animal. And this is the group that is on the central oxygen of
|
|
mescaline.
|
|
|
|
It is customary to refer to homologs (bigger-by-one) of methanol by
|
|
their classical chemical names, so the natural extension of methyl is
|
|
ethyl, and that of mescaline would be escaline. One carbon-chain on
|
|
the 4-position oxygen becoming a two-carbon chain. This is all
|
|
entymologically appealing, but there is no botanical support for any
|
|
of it. The ethyl group is much more rare in nature. It is just a
|
|
happy coincidence that mescaline (the plant), and methyl (the alkyl
|
|
group involved), and methoxy (the group on the 4-position of the
|
|
aromatic ring) all happen to start with the letter RMS.
|
|
|
|
Very few of the homomescaline phenethylamines have been synthesized as
|
|
their three-carbon chain counterparts, the corresponding analogues of
|
|
amphetamine. And only three of them have been explored in man (four,
|
|
if you count the amphetamine analogue of mescaline itself, TMA). The
|
|
obvious names for these compounds have, unfortunately, already been
|
|
used. It would be logical to use the letter M for a methoxy, and the
|
|
letter E for ethoxy, etc. and simply read the groups from around the
|
|
ring. But this is the naming system for the 2,4,5-trisubstituted
|
|
amphetamines. MEM is, for example, 2,5-dimethoxy-4-ethoxyamphetamine
|
|
(in sequence, methoxy, ethoxy, methoxy reading around the ring, and a
|
|
fascinating compound talked about at length in this book), so this
|
|
term cannot represent 3,5-dimethoxy-4-ethoxyamphetamine.
|
|
|
|
A truly simple code employs the length of the carbon chain. The
|
|
phenethylamine chain is two carbons long, and the amphetamine chain is
|
|
three carbons long.
|
|
|
|
If a drug has been initially developed (and initially named) as an
|
|
amphetamine derivative (three carbon chain) then the two-carbon chain
|
|
analogue will use the original name (or a symbolic part of it) with
|
|
the term 2C ahead of it. The two-carbon analogue of DOB (a
|
|
three-carbon chain compound) will become 2C-B. DOI becomes 2C-I, DON
|
|
becomes 2C-N, and DOET becomes 2C-E. Each of these is a substituted
|
|
amphetamine derivative lacking one carbon atom, thus becoming a
|
|
phenethylamine derivative. Most of these have 2,4,5-substitution
|
|
patterns.
|
|
|
|
And if a drug has been initially developed (and initially named) as a
|
|
phenethylamine derivative (two carbon chain) then the three-carbon
|
|
chain analogue will use the original name with the term 3C ahead of
|
|
it. The three carbon analogue of E (escaline, a two-carbon chain
|
|
compound) will become 3C-E. P becomes 3C-P and CPM becomes 3C-CPM.
|
|
Most of these have 3,4,5-substitution patterns.
|
|
|
|
Thus, R2-CS implies that a known amphetamine drug has been shortened
|
|
to a phenethylamine, and R3-CS inplies that a known phenethylamine has
|
|
been lengthened to an amphetamine. A great number of the former have
|
|
been made and have proven to be most rewarding. Only a few of the
|
|
latter are known, but most of them will eventually prove to be potent
|
|
psychedelics.

#73 EEE; 2,4,5-TRIETHOXYAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 13.3 g 3,4-diethoxyphenol (see the recipe for
|
|
MEE for its preparation) in 20 mL MeOH, and a solution of 4.8 g KOH in
|
|
100 mL hot MeOH were combined. There was added 8.2 g ethyl bromide
|
|
and the mixture was held at reflux on the steam bath for 2 h. The
|
|
reaction was quenched by the addition of three volumes H2O, made
|
|
strongly basic by the addition of 10% NaOH, and extracted with 3x150
|
|
mL CH2Cl2. The solvent was removed from the pooled extracts under
|
|
vacuum giving a residue of 9.1 g 1,2,4-triethoxybenzene that
|
|
solidified to a crystalline mass. The mp was 28.5-29.5 !C, but the
|
|
infra-red analysis showed the presence of unreacted phenol. The
|
|
CH2Cl2 solution was again washed thoroughly with 10% NaOH and, after
|
|
removal of the solvent, the solidified residue weighed 6.0 g and
|
|
appeared free of impurities. The mp of this sample was 33-34 !C.
|
|
|
|
To a mixture of 10.5 g N-methyl formanilide and 11.9 g POCl3 that had
|
|
incubated at room temperature for 0.5 h (it had become quite red in
|
|
color) there was added 6.4 g of the solid ether,
|
|
1,2,4-triethoxybenzene. The mixture was heated on the steam bath for
|
|
2.5 h, then poured into 500 mL of shaved ice. After a few minutes
|
|
stirring, crystals appeared. The reaction was allowed to stand for a
|
|
few h, then filtered and sucked as dry as possible. The damp 14.4 g
|
|
of slate-green crude solids were dissolved in 30 mL boiling MeOH, and
|
|
allowed to cool to room temperature overnight. Filtration of the
|
|
cream-colored product, and air drying, gave 6.1 g of
|
|
2,4,5-triethoxybenzaldehyde with a mp of 94-95 !C. A solution
|
|
containing 0.5 g of this aldehyde and 0.4 g malononitrile in 7 mL
|
|
absolute EtOH was treated with three drops of triethylamine. There
|
|
was an immediate formation of granular yellow crystals of
|
|
2,4,5-triethoxybenzalmalononitrile which, on filtering and air drying,
|
|
weighed 0.4 g and had a mp of 169-170 !C.
|
|
|
|
A solution of 5.0 g 2,4,5-triethoxybenzaldehyde and 2.6 g nitroethane
|
|
in 14.8 g glacial acetic acid was treated with 1.6 g anhydrous
|
|
ammonium acetate and heated on the steam bath for 2 h. The addition
|
|
of an equal volume of H2O gave a slightly turbid solution which, upon
|
|
the administration of a small amount of externally developed seed,
|
|
smoothly set up as orange crystals as the reaction mix returned to
|
|
room temperature. The product was removed by filtration, washed with
|
|
a little 50% acetic acid, and allowed to air dry to constant weight.
|
|
There was thus obtained 2.5 g of fluffy yellow-orange (almost yellow)
|
|
crystals of 2-nitro-1-(2,4,5-triethoxyphenyl)propene with a mp of
|
|
91-92.5 !C. Anal. (C15H21NO5) C,H.
|
|
|
|
To a gently refluxing suspension of 1.7 g LAH in 200 mL anhydrous Et2O
|
|
under a He atmosphere, there was added 2.5 g
|
|
2-nitro-1-(2,4,5-triethoxyphenyl)propene by allowing the condensing
|
|
Et2O to drip into a shunted Soxhlet thimble containing the
|
|
nitrostyrene, thus effectively adding a warm saturated solution of the
|
|
nitrostyrene dropwise. Refluxing was maintained for 5 h, and then the
|
|
reaction mixture was cooled with an external ice bath. The excess
|
|
hydride was destroyed by the cautious addition of 300 mL 1.5 N H2SO4.
|
|
When the aqueous and Et2O layers were finally clear, they were
|
|
separated, and 50 g of potassium sodium tartrate were dissolved in the
|
|
aqueous fraction. Aqueous NaOH was then added until the pH was above
|
|
9, and this was extracted with 3x200 mL CH2Cl2. Removal of the
|
|
solvent under vacuum produced an amber oil that was dissolved in
|
|
anhydrous Et2O and saturated with anhydrous HCl gas. After a few min
|
|
delay, there com-menced the separation of fine white crystals of
|
|
2,4,5-triethoxyamphetamine hydro-chloride, (EEE). These weighed,
|
|
after filtration, Et2O washing, and air drying to constant weight,
|
|
1.75 g and had a mp of 167-168 !C, with prior softening at 162 !C.

EXTENSIONS AND COMMENTARY: This amphetamine, the final item on the
|
|
ethoxy homologue of TMA-2 project, has never been tried in man. I do
|
|
not know how it tastes, but I suspect that it is probably bitter. An
|
|
interesting sidelight concerning this project, and one which can serve
|
|
as a measure of the enthusiasm that went into it, is that (except for
|
|
the 2-ethoxy homologue EMM) all of the possible ethoxy homologues of

#74 EEM; 2,4-DIETHOXY-5-METHOXYAMPHETAMINE
|
|
|
|
SYNTHESIS: To a solution of 12.3 g 3-ethoxy-4-methoxyphenol (see
|
|
recipe for MEM for the preparation of this phenol) in 20 mL MeOH,
|
|
there was added a warm solution of 4.8 g KOH in 100 mL MeOH. There
|
|
was then added 8.2 g ethyl bromide, and the mixture held at reflux on
|
|
the steam bath. Within 0.5 h, severe bumping ensued. An additional 3
|
|
g ethyl bromide were added, refluxing continued for another 0.5 h,
|
|
then the reaction mixture was allowed to come to room temperature and
|
|
to stand overnight. It was poured into 3 volumes H2O which produced
|
|
crystals spontaneously. There was added additional base, and the
|
|
mixture was extracted with 3x150 mL CH2Cl2. Removal of the solvent
|
|
from the pooled extracts under vacuum gave 6.4 g of
|
|
2,4-diethoxyanisole as tan crystals with a mp of 48-48.5 !C.
|
|
|
|
A mixture of 10.9 g N-methylformanilide and 12.3 g POCl3 was allowed
|
|
to stand at room temperature for 0.5 h producing a deep red claret
|
|
color. There was then added 6.2 g 2,4-diethoxyanisole and the mixture
|
|
was heated on the steam bath for 2 h. All was poured into 200 g
|
|
chipped ice, and stirred mechanically. The dark viscous gummy oil
|
|
gradually became increasingly granular and finally appeared as
|
|
jade-green solids. These were removed by filtration and washed with
|
|
H2O, giving a wet cake weighing 18 g and having a mp (from a porous
|
|
plate) of 95.5-96.5 !C. The entire crop was recrystallized from 75 mL
|
|
boiling MeOH which gave, after filtering, washing lightly with cold
|
|
MeOH, and air drying, 5.4 g of 2,4-diethoxy-5-methoxybenzaldehyde with
|
|
a mp of 98-99 !C. A solution of 0.2 g of this aldehyde, and 0.3 g
|
|
malononitrile in 2.0 mL warm EtOH was treated with a drop of
|
|
triethyl-amine. There was an immediate generation of crystals which
|
|
were removed by filtration, EtOH-washed, and dried to constant weight.
|
|
The bright yellow needles of 2,4-diethoxy-5-methoxybenzalmalononitrile
|
|
weighed 0.15 g and had a mp of 172-172.5 !C.
|
|
|
|
A solution of 5.0 g 2,4-diethoxy-5-methoxybenzaldehyde in 16 g glacial
|
|
acetic acid was treated with 2.7 g nitroethane followed by 1.7 g
|
|
anhydrous ammonium acetate. The mixture was heated for 2.5 h on the
|
|
steam bath, then removed and diluted with a equal volume of H2O. With
|
|
cooling there was the generation of a heavy crop of orange crystals
|
|
which was removed, washed with 50% acetic acid, and sucked as dry as
|
|
possible. The product had a mp of 97-104 !C, and there was
|
|
spectrographic evidence of some unreacted starting aldehyde. A small
|
|
sample was recrystallized from boiling MeOH, with considerable loss,
|
|
to give an analytical sample of
|
|
1-(2,4-diethoxy-5-methoxyphenyl)-2-nitropropene as orange-yellow
|
|
crystals with a mp of 112-113 !C. Anal. (C14H19NO5) C,H. The
|
|
unpurified first crop was employed in the following synthesis of the
|
|
corresponding amphetamine.
|
|
|
|
To a gently refluxing suspension of 2.9 g LAH in 400 mL anhydrous Et2O
|
|
under a He atmosphere, there was added 4.0 g of impure
|
|
1-(2,4-diethoxy-5-methoxyphenyl)-2-nitropropene by allowing the
|
|
condensing ether to drip into a shunted Soxhlet thimble apparatus
|
|
containing the nitrostyrene. This effectively added a warm saturated
|
|
solution of the nitrostyrene dropwise over the course of 1 h.
|
|
Refluxing was maintained for 5 h and the reaction mixture was cooled
|
|
with an external ice bath with the stirring continued. The excess
|
|
hydride was destroyed by the cautious addition of 400 mL of 1.5 N
|
|
H2SO4. When the aqueous and Et2O layers were finally clear, they were
|
|
separated, and 100 g of potassium sodium tartrate was dissolved in the
|
|
aqueous fraction. Aqueous NaOH was then added until the pH was above
|
|
9, and this was then extracted with 3x150 mL CH2Cl2. Removal of the
|
|
solvent under vacuum produced 2.7 g of a pale amber oil that was
|
|
dissolved in 300 mL anhydrous Et2O and saturated with anhydrous HCl
|
|
gas. After a few minutes delay, there commenced the separation of
|
|
fine white crystals of 2,4-diethoxy-5-methoxyamphetamine hydrochloride
|
|
(EEM). After the crystallization was complete, these were removed by
|
|
filtration, washed with Et2O and air dried, providing 2.55 g of a fine
|
|
white crystalline solid with mp 158-159 !C. Anal. (C14H24ClNO3)
|
|
C,H,N.

|
EXTENSIONS AND COMMENTARY: This particular identity and arrangement of
|
|
the alkoxy groups on the amphetamine molecule, EEM, is a totally
|
|
unexplored molecule. It is reasonable to assume that it would be way
|
|
down in potency, but there is no way of guessing what the nature of
|
|
its activity might be at the dosage that would be active.

#75 EME; 2,5-DIETHOXY-4-METHOXYAMPHETAMINE
|
|
|
|
SYNTHESIS: To a solution of 14.0 g 4-ethoxy-3-methoxyphenol (see the
|
|
recipe for MME for the preparation of this starting material) in an
|
|
equal volume of EtOH, there was added a solution of 5.3 g KOH in 100
|
|
mL hot MeOH. This was followed with 9.1 g ethyl bromide, and the
|
|
mixture was held at reflux for 2 h. The first deposition of KBr was
|
|
apparent in 5 min, and there was rather severe bumping by the end of
|
|
the reaction. The mixture was diluted with 3 volumes H2O and 1 volume
|
|
5% NaOH, and extracted with 2x200 mL Et2O. The extracts were pooled,
|
|
and the solvent removed under vacuum, yielding 14.3 g of a pale amber
|
|
oil that set to crystals of 2,5-diethoxyanisole with a mp of 44-45 !C.
|
|
The compound had been reported in the literature from the action of
|
|
diethyl sulfate on methoxyhydroquinone.
|
|
|
|
To a mixture of 24.1 g N-methylformanilide and 27.3 g POCl3 that had
|
|
been allowed to stand at room temperature until strongly red-colored
|
|
(about 0.5 h) there was added 13.8 g solid 2,5-diethoxyanisole and the
|
|
mixture was heated on the steam bath for 2 h. The black, thick
|
|
reaction product was poured over chipped ice and, with continuous
|
|
stirring, the color lightened and there was the formation of a
|
|
yellowish powder. After a few h standing, this was removed by
|
|
filtration and sucked as dry as possible. The 32 g of damp product
|
|
showed the presence of isomeric contaminatiion by GC, and the aqueous
|
|
mother liquor, upon extraction with CH2Cl2 and concentration, showed
|
|
yet more aldehyde-like impurities. The isolated solids were
|
|
recrystallized from 125 mL boiling MeOH giving 15.8 g yellowish
|
|
crystals (wet weight) that still showed detectable impurities by GC.
|
|
A second recrystallization from 100 mL boiling MeOH gave off-white
|
|
fluffy crystals of 2,5-diethoxy-4-methoxybenzaldehyde which weighed,
|
|
after air drying, 8.5 g. The mp was 109-110 !C. The combined mother
|
|
liquors from the two MeOH crystallizations were stripped of solvent,
|
|
and the resulting solid mass crystallized again from MeOH to give a
|
|
second crop of aldehyde, 5.7 g, with a mp of 110-111 !C. A solution
|
|
of 1.0 g of this aldehyde and 0.7 g malononitrile in 40 mL warm
|
|
absolute EtOH was treated with a few drops of triethylamine. In a
|
|
minute or so, there was the formation of crystals. These were removed
|
|
by filtration, washed with EtOH, and air dried, giving 0.6 g of
|
|
2,5-diethoxy-4-methoxybenzalmalononitrile as brilliant yellow crystals
|
|
with a mp of 156.5-158 !C.
|
|
|
|
A solution of 6.7 g 2,5-diethoxy-4-methoxybenzaldehyde in 21 g glacial
|
|
acetic acid was treated with 3.1 g nitroethane and 1.93 g anhydrous
|
|
ammonium acetate, and heated on the steam bath for 2.5 h. The
|
|
addition of a small amount of H2O to the hot reaction mixture
|
|
instituted crystallization of an orange product which, after the
|
|
mixture had come to room temperature and stood for several h, was
|
|
removed by filtration, H2O washed, and air dried. The product,
|
|
1-(2,5-diethoxy-4-methoxyphenyl)-2-nitropropene, was dull orange in
|
|
color, weighed 3.0 g and had a mp of 84-86 !C. An analytical sample
|
|
from toluene had a mp of 85-86 !C. Anal. (C14H19NO5) C,H.
|
|
|
|
To a gently refluxing suspension of 2.0 g LAH in 250 mL anhydrous Et2O
|
|
under a He atmosphere, there was added 2.8 g
|
|
1-(2,5-diethoxy-4-methoxyphenyl)-2-nitropropene by allowing the
|
|
condensing Et2O to drip into a shunted Soxhlet thimble containing the
|
|
nitrostyrene. This effectively added a warm saturated solution of the
|
|
nitrostyrene dropwise. The addition took 1 h and the refluxing was
|
|
continued for an additional 6 h. The reaction mixture was brought
|
|
down to ice-bath temperature, and the excess hydride was destroyed by
|
|
the cautious addition of 150 mL 1.5 N H2SO4. When the aqueous and
|
|
Et2O layers were finally clear, they were separated and 50 g of
|
|
potassium sodium tartrate were dissolved in the aqueous fraction.
|
|
Aqueous NaOH was then added until the pH was >9, and this was then
|
|
extracted with 3x150 mL CH2Cl2. Removal of the solvent under vacuum
|
|
produced 2.3 g of a clear white oil that was dissolved in 300 mL
|
|
anhydrous Et2O and saturated with anhydrous HCl gas. At first the
|
|
solution remained completely clear, and finally there was the start of
|
|
the formation of fine white crystals. When the crystallization was
|
|
complete, these solids were removed by filtration, Et2O washed, and
|
|
air dried. There was thus obtained 2.2 g of
|
|
2,5-diethoxy-4-methoxyamphetamine hydrochloride (EME) with a mp of
|
|
162-164 !C with prior softening at 154 !C. Anal. (C14H24ClNO3) C,H,N.

EXTENSIONS AND COMMENTARY: This is another of the collection of all
|
|
possible ethoxy homologues of TMA-2. The latter and heavier members
|
|
of this series were synthesized and completed before the directions of
|
|
biological activity had become evident from the earlier ones. This
|
|
compound has never been assayed, and it is a reasonable guess that it
|
|
will have a very low potency, with hints of toxicity at higher dose
|
|
levels. I suspect that it will never be assayed, certainly not by me.

#76 EMM; 4,5-DIMETHOXY-2-ETHOXYAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 166 g 3,4-dimethoxybenzaldehyde in 600 mL
|
|
acetic acid was well stirred, and brought up to an internal
|
|
temperature of exactly 25 !C. There was added, in very small
|
|
portions, a 40% solution of peracetic acid in acetic acid. The
|
|
evolved heat was removed with an external ice bath, and the rate of
|
|
addition was dictated by the requirement that the internal temperature
|
|
should not exceed 25 !C. A total of 210 g of the 40% peracetic acid
|
|
was used. The reaction mixture was poured into 3 L H2O, and the
|
|
acetic acid neutralized by the addition of solid K2CO3. The neutral
|
|
aqueousphase was extracted with 5x150 mL Et2O, and the solvent from
|
|
the pooled extracts was removed under vacuum. To the red-colored
|
|
residue there was added 300 mL 10% NaOH, and the mixture was heated
|
|
for 1 h on the steam bath. This was cooled, washed once with CH2Cl2,
|
|
acidified with HCl, and extracted with 5x150 mL Et2O. The pooled
|
|
extracts were washed once with saturated NaHCO3 (which removed most of
|
|
the color) and the removal of the solvent under vacuum gave 105 g of
|
|
3,4-dimethoxyphenol as an amber oil that slowly set up to crystals.
|
|
|
|
The above crude 3,4-dimethoxyphenol was dissolved in 200 mL EtOH, and
|
|
treated with a solution of 38.1 g KOH in 300 mL hot EtOH. The clear
|
|
solution of the potassium salt was a deep red color, and was promptly
|
|
treated with 94.3 g allyl bromide, at a rate commensurate with the
|
|
exothermic reaction. The mixture was held at reflux for 2 h. This
|
|
was then added to 1 L H2O and extracted with 5x100 mL Et2O. The
|
|
extracts were pooled, and removal of the solvent under vacuum gave a
|
|
residue of 98 g of a black oil. This was distilled at 104-108 !C at
|
|
0.7-1.0 mm/Hg to give 59.3 g 1-allyloxy-3,4-dimethoxybenzene as a pale
|
|
yellow oil with a greenish cast.
|
|
|
|
A total of 59 g of the neat 1-allyloxy-3,4-dimethoxybenzene was
|
|
provided with an internal thermometer, and heated with an open flame.
|
|
The color quickly became purple, then lightened to a red at 70 !C, and
|
|
finally to a pale pink by 210 !C. At 240 !C an exothermic reaction
|
|
set in with the temperature going up to almost 290 !C. It was held in
|
|
the 270-280 !C range for several min, then allowed to return to room
|
|
temperature. GC analysis showed two peaks, the second and major one
|
|
being the desired 1,2,4,5-isomer. A small sample was caught by
|
|
prep-GC, and it successfully seeded the crude Claissen rearrangement
|
|
product. The isolated 2-allyl-4,5-dimethoxyphenol, pressed on a
|
|
porous plate, had a mp of 39.5-40.5 !C which was improved to 41.5-42
|
|
!C by recrystallization from hexane.
|
|
|
|
To a solution of 9.7 g 2-allyl-4,5-dimethoxyphenol in a few mL EtOH,
|
|
there was added a solution of 2.8 g KOH in 25 mL boiling EtOH followed
|
|
by 5.5 g ethyl bromide. The mixture was held at reflux for 3.5 h and
|
|
then poured into 200 mL H2O and extracted with 3x100 mL CH2Cl2.
|
|
Pooling the extracts and removal of the solvent under vacuum gave a
|
|
residue of 10.4 g of 4,5-dimethoxy-2-ethoxy-1-allylbenzene as a clear,
|
|
mobile oil. It was substantially a single component by GC and was
|
|
used in the following isomerization step without further purification.
|
|
|
|
A solution of 9.4 g 4,5-dimethoxy-2-ethoxy-1-allylbenzene in 10 mL
|
|
EtOH was treated with 20 g flaked KOH, and heated on the steam bath.
|
|
The progress of the isomerization was followed by the assay of
|
|
isolates by GC. After 5 h, the reaction mixture was poured into 250
|
|
mL H2O which immediately generated a pasty solid. This was sucked
|
|
free of solvent and other liquids on a sintered funnel, giving 5.5 g
|
|
of trans-4,5-dimethoxy-2-ethoxy-1-propenylbenzene as an amber solid
|
|
with a mp of 65-67 !C. A small analytical sample from hexane had a mp
|
|
of 68 !C.
|
|
|
|
A solution of 5.0 g trans-4,5-dimethoxy-2-ethoxy-1-propenylbenzene in
|
|
27 g acetone that contained 2.2 g pyridine was magnetically stirred
|
|
and cooled to 0 !C. There was then added 4.5 g tetranitromethane and,
|
|
after 2 minutes stirring at this temperature, the reaction mixture was
|
|
quenched with a solution of 1.5 g KOH in 26 mL H2O. The reaction
|
|
mixture remained a clear deep orange color, and additional H2O was
|
|
required to institute crystallization. There was the slow deposition
|
|
of bright yellow crystals of
|
|
1-(4,5-dimethoxy-2-ethoxyphenyl)-2-nitro-propene which weighed, after
|
|
EtOH washing and air drying to constant weight of 4.4 g. The mp was
|
|
75-76 !C.
|
|
|
|
To a gently refluxing suspension of 3.5 g LAH in 250 mL anhydrous Et2O
|
|
under a He atmosphere, there was added 3.9 g
|
|
1-(4,5-dimethoxy-2-ethoxyphenyl)-2-nitropropene by allowing the
|
|
condensing Et2O to drip into a shunted Soxhlet apparatus with the
|
|
thimble containing the nitrostyrene. This effectively added a warm
|
|
saturated solution of the nitrostyrene dropwise; the nitrostyrene was
|
|
very soluble in Et2O. Refluxing was maintained for 2.5 h and the
|
|
reaction continued to stir at room temperature for an additional 3.5
|
|
h. The excess hydride was destroyed by the cautious addition of 225
|
|
mL 1.5 N H2SO4. When the aqeous and Et2O layers were finally clear,
|
|
they were separated, and 75 g of potassium sodium tartrate was
|
|
dissolved in the aqueous fraction. Aqueous NaOH was then added until
|
|
the pH was >9, and this was then extracted with 3x100 mL CH2Cl2.
|
|
Evaporation of the solvent under vacuum produced 2.8 g of a clear,
|
|
almost colorless oil that was dissolved in anhydrous Et2O and
|
|
saturated with anhydrous HCl gas. This initially generated a solid
|
|
that then oiled out. After a few minutes stirring, this began to
|
|
solidify again and it finally transformed into a loose fine white
|
|
solid. This was recrystallized by dissolution in 50 mL warm IPA
|
|
followed by dilution with 300 mL Et2O. After a few minutes, crystals
|
|
of 4,5-dimethoxy-2-ethoxyamphetamine hydrochloride (EMM) formed which
|
|
were removed by filtration, Et2O washed, and air dried. These weighed
|
|
2.7 g and had a mp of 171-172 !C. Anal. (C13H22ClNO3) C,H,N.
|
|
|
|
DOSAGE: greater than 50 mg.
|
|
|

DURATION: unknown.
|
|
|
|
QUALITATIVE COMMENTS: (with 50 mg) There were no effects.
|
|
|
|
EXTENSIONS AND COMMENTARY: This was the first of the ethoxy homologues
|
|
of TMA-2, and it was immediately (well, within a couple of months) run
|
|
up from an initial dab to 25 milligrams. This was in early 1963, and
|
|
the lack of activity of EMM was keenly disappointing. This was a
|
|
level at which the prototype, TMA-2, was very active, and the
|
|
conclusion was that maybe any change on the molecule would result in a
|
|
loss of activity. So this approach was shelved for a while, and all
|
|
efforts were directed into the relocation, rather than the elongation,
|
|
of the methoxy groups. A few months later, the ethoxy question was
|
|
addressed again, and the discovery of MEM rekindled full interest in
|
|
this ethoxy question.

#77 ETHYL-J; 2-ETHYLAMINO-1-(3,4-METHYLENEDIOXYPHENYL)BUTANE;
|
|
|
|
N-ETHYL-1-(1,3-BENZODIOXOL-5-YL)-2-BUTANAMINE
|
|
|
|
SYNTHESIS: A stirred solution of 9.0 g
|
|
1-(3,4-methylenedioxyphenyl)-2-butanone (see the recipe for J for its
|
|
preparation) in 150 mL MeOH was treated with 9.0 g ethylamine
|
|
hydrochloride, 4.0 g anhydrous NaOAc, and 3.0 g sodium
|
|
cyanoborohydride. The pH was maintained between 6 and 7 by the
|
|
periodic addition of HCl. After the base formation had stabilized,
|
|
there was added an additional 9.0 g ethylamine hydrochloride, 9.0 g
|
|
NaOAc and 2.0 g sodium cyanoborohydride. With continuous stirring,
|
|
there was HCl added over the course of 1 h until the final pH was
|
|
approximately 2. The reaction mixture was poured into 700 mL dilute
|
|
NaOH, and extracted with 3x75 mL CH2Cl2. These extracts were pooled,
|
|
and back-extracted with dilute H2SO4. This was washed with 2x50 mL
|
|
CH2Cl2, then made basic with dilute NaOH and extracted with 2x75 mL
|
|
CH2Cl2. Removal of the solvent under vacuum gave a 0.81 g residue
|
|
which was dissolved in 10 mL IPA. Neutralization with concntrated HCl
|
|
formed white crystals spontaneously. These were diluted with Et2O,
|
|
filtered, Et2O washed and air dried to provide 0.85 g
|
|
2-ethylamino-1-(3,4-methylenedioxy-phenyl)butane hydrochloride
|
|
(ETHYL-J), with mp of 176-177 !C. Anal. (C13H20ClNO2) C,H. The
|
|
neutral fraction that remained in the organic phase following the
|
|
dilute sulfuric acid extraction, was recovered by removal of the
|
|
solvent under vacuum. There was obtained about 5 g of an amber liquid
|
|
that was largely 2-hydroxy-1-(3,4-methylenedioxyphenyl)butane.
|
|
|
|
DOSAGE: greater than 90 mg.
|
|
|
|
DURATION: probably short.
|
|
|
|
QUALITATIVE COMMENTS: (with 65 mg) Perhaps aware at 20 minutes.
|
|
Definitely aware at 45 minutes. Diffusing to nothing at 3-4 hours.
|
|
|
|
(with 90 mg) I am somewhere between 1 and +. And everything became
|
|
lost in the evening with a couple of glasses of wine and talk that
|
|
went on to 3 AM.
|
|
|
|
EXTENSIONS AND COMMENTARY: And nothing higher has ever been looked at.
|
|
If the analogy with the amphetamine counterparts (J with MDA, METHYL-J
|
|
with MDMA, and this, with MDE) were to hold up (a drop of about a
|
|
third in potency with the lengthening of the chain by a carbon atom),
|
|
one might guess that this compound would be an interesting intoxicant,
|
|
but probably not until you got up into the area at or above a 200

handle. Some day, maybe.

#78 ETHYL-K; 2-ETHYLAMINO-1-(3,4-METHYLENEDIOXYPHENYL)PENTANE;
|
|
|
|
N-ETHYL-1-(1,3-BENZODIOXOL-5-YL)-2-PENTYLAMINE
|
|
|
|
SYNTHESIS: A solution of 120 mg mercuric chloride in 160 mL H2O was
|
|
poured over 4.7 g aluminum foil (Reynolds Wrap, regular weight, cut
|
|
into 1 inch squares) and allowed to stand until the amalgamation was
|
|
well underway (about 30 min). The H2O was then drained and the foil
|
|
washed with 2x200 mL H2O with thorough draining. There was then
|
|
added, in sequence and with good swirling and agitation between each
|
|
addition, 8.5 g ethylamine hydrochloride dissolved in 7 mL H2O, 21 mL
|
|
IPA, 17 mL 25% NaOH, 7.1 g 1-(3,4-methylenedioxyphenyl)-2-pentanone
|
|
(see the recipe for METHYL-K for its preparation), and finally 40 mL
|
|
IPA. The reaction mixture was periodically heated on the steam bath
|
|
to keep the reaction moving and active. After all the metal had been
|
|
consumed, the mixture was filtered, and the filter cake washed with
|
|
MeOH. The solvent was removed from the combined filtrate and
|
|
washings, and the residue suspended in 800 mL dilute HCl. This was
|
|
washed with 3x100 mL Et2O, made basic with 25% NaOH, and extracted
|
|
with 3x100 mL CH2Cl2. The pooled extracts were stripped of solvent
|
|
under vacuum yielding a residue of 6.3 g of an amber oil. This was
|
|
distilled at 115-125 !C at 0.4 mm/Hg to give 5.61 g of an almost white
|
|
liquid which was dissolved in 28 mL IPA, neutralized with concentrated
|
|
HCl, and diluted with 100 mL anhydrous Et2O. The resulting clear
|
|
solution became cloudy, then set up in a cottage cheese texture, and
|
|
then all broke up to a beautiful loose solid. This was filtered, Et2O
|
|
washed and air dried to give 5.99 g
|
|
2-ethylamino-1-(3,4-methylenedioxyphenyl)pentane hydrochloride
|
|
(ETHYL-K) with a mp of 157-158 !C. Anal. (C14H22ClNO2) C,H.
|
|
|
|
DOSAGE: (greater than 40 mg).
|
|
|
|
DURATION: unknown.
|
|
|
|
QUALITATIVE COMMENTS: (with 40 mg) There was a paresthetic twinge in
|
|
my shoulder area at about an hour Q other than that, absolutely
|
|
nothing.
|
|
|
|
EXTENSIONS AND COMMENTARY: And that is as high a dose as has
|
|
apparently ever been tried with ETHYL-K. The compounds with the
|
|
hexane chain (L-series) rather than the pentane chain of the K-series
|
|
have been made, but they have been spun into the recipe for METHYL-K.

|
|
6-(2-AMINOPROPYL)-5-METHOXY-2-METHYL-2,3-DIHYDROBENZOFURAN
|
|
|
|
SYNTHESIS: To a solution of 43.2 g KOH pellets in 250 boiling EtOH
|
|
there was added 96 g 4-methoxyphenol followed by the slow addition of
|
|
131.2 g allyl bromide, and the mixture was held under refluxing
|
|
conditions for 16 h. After cooling, the reaction was added to 1.6 L
|
|
H2O, and made strongly basic with 25% NaOH. This was extracted with
|
|
3x100 mL CH2Cl2, the extracts pooled, washed once with dilute NaOH and
|
|
then once with dilute HCl. Removal of the solvent under vacuum gave
|
|
93.8 g of 4-allyloxyanisole as a pale amber oil, which was used in the
|
|
following reaction without further purification.
|
|
|
|
A round-bottomed flask containing 93 g crude 4-allyloxyanisole was
|
|
equipped with an immersed thermometer and heated with an external
|
|
flame until an exothermic reaction set in at 230 !C. The temperature
|
|
rose to 270 !C and it was maintained there with the flame for five
|
|
minutes. After cooling to room temperature, the reaction mix was
|
|
poured into 2 L H2O and made strongly basic with the addition of 25%
|
|
NaOH. This dark aqueous phase was washed with 2x200 mL CH2Cl2, and
|
|
then acidified with HCl. This was then extracted with 2x200 mL
|
|
CH2Cl2, and the pooled extracts washed first with saturated NaHCO3 and
|
|
then with H2O. Removal of the solvent under vacuum gave 65.6 g of
|
|
2-allyl-4-methoxyphenol as a clear, amber oil. To a solution of 1.66
|
|
g of this crude phenol in 5 mL hexane with just enough CH2Cl2 added to
|
|
effect a clear solution, there was added 1.3 g phenyl isocyanate
|
|
followed with three drops of triethylamine. An exothermic reaction
|
|
ensued which spontaneously deposited white crystals. These was
|
|
removed and hexane washed to give 2-allyl-4-methoxyphenyl N-phenyl
|
|
carbamate, with a mp of 88-89 !C. The acetate ester, from the phenol
|
|
and acetic anhydride in pyridine, did not crystallize.
|
|
|
|
To a solution of 37.7 g 2-allyl-4-methoxyphenol in 125 mL glacial
|
|
acetic acid there was added 19 g zinc chloride followed with 63 mL
|
|
concentrated HCl. The mixture was held at reflux temperature for 40
|
|
min, then cooled to room temperature, diluted with 300 mL H2O, and
|
|
extracted with 2x200 mL CH2Cl2. The pooled extracts were washed
|
|
repeatedly with 8% NaOH until the washings remained basic. Removal of
|
|
the solvent under vacuum gave a clear pale yellow oil that was
|
|
distilled at the water pump. A fraction boiling at 150-165 !C was
|
|
5-methoxy-2-methyl-2,3-dihydrobenzofuran which weighed 25 g and which
|
|
was a highly refractive colorless oil. The infra-red spectrum
|
|
indicated that some small amount of hydroxy group was present, but the
|
|
NMR spectrum was in complete accord with the benzofuran structure. A
|
|
higher cut in this distillation gave 4.5 g of a phenolic product
|
|
tentatively assigned the structure of 4-methoxy-2-propenylphenol. The
|
|
target dihydrobenzo-furan has also been synthesized from the open-ring
|
|
o-allyl phenol in acetic acid solution with the addition of a
|
|
catalytic amount of concentrated H2SO4.
|
|
|
|
To a half-hour pre-incubated mixture of 69 g POCl3 and 60 g
|
|
N-methylformanilide there was added 29.0 g
|
|
5-methoxy-2-methyl-2,3-dihydrobenzofuran and the mixture was heated on
|
|
the steam bath for 2 h. The reaction mixture was poured into 1 L H2O,
|
|
and allowed to stir overnight. The brown gummy solids were removed by
|
|
filtration, and air dried as completely as possible. These weighed 32
|
|
g and were shown by GC on OV-17 to consist of two benzaldehyde isomers
|
|
in a ratio of 7:2. This was triturated under 18 mL MeOH, and the
|
|
undissolved solids removed by filtration and washed with 6 mL
|
|
additional MeOH. The mother liquor and washings were saved. The 17.8
|
|
g of dull yellow solids that were obtained were repeatedly extracted
|
|
with 75 mL portions of boiling hexane (4 extracts were required) and
|
|
each extract, on cooling, deposited yellow crystals of the major
|
|
aldehyde. The dried crystals of
|
|
6-formyl-5-methoxy-2-methyl-2,3-dihydrobenzofuran were combined (9.5
|
|
g) and had a mp of 80-82 !C. The methanol washes saved from above
|
|
were stripped of solvent, and the sticky, orange solids that remained
|
|
were enriched in the minor aldehyde isomer (3:2 ratio). Several
|
|
injections of this crude material into a preparative GC OV-17 column
|
|
gave sufficient quantities of the RwrongS isomer for NMR
|
|
characterization. The 2-methyl group was intact (eliminating the
|
|
possibility of a dihydrobenzopyran isomer) and the ring meta-proton
|
|
splitting required that the formyl group be in the benzofuran
|
|
7-position. This crystalline solid was, therefore,
|
|
7-formyl-5-methoxy-2-methyl-2,3-dihydrobenzofuran.
|
|
|
|
A solution of 9 g of 6-formyl-5-methoxy-2-methyl-2,3-dihydrobenzofuran
|
|
in 35 mL glacial acetic acid was treated with 6 mL of nitroethane
|
|
followed with 3.1 g anhydrous ammonium acetate. This mixture was
|
|
heated on the steam bath for 4 h, diluted with half its volume with
|
|
warm H2O, and seeded with a bit of product that had been obtained
|
|
separately. The slightly turbid solution slowly crystallized as it
|
|
cooled, and was finally held at 0 !C for several h. The deep orange
|
|
product was removed by filtration, washed with 50% acetic acid, and
|
|
air dried to constant weight. There was thus obtained 7.0 g
|
|
5-methoxy-2-methyl-6-(2-nitro-1-propenyl)-2,3-dihydrobenzofuran with a
|
|
mp of 89-90 !C from MeOH.
|
|
|
|
A suspension of 5.0 g LAH in 500 mL of well stirred anhydrous Et2O at
|
|
a gentle reflux, was treated with a warm, saturated solution of 7.0 g
|
|
5-methoxy-2-methyl-6-(2-nitro-1-propenyl)-2,3-dihydrobenzofuran in
|
|
Et2O added dropwise. The mixture was kept at reflux temperature for
|
|
36 h, allowed to stand 2 days, and then the excess hydride destroyed
|
|
by the cautious addition of 500 mL 6% H2SO4. The phases were
|
|
separated, and the aqueous phase washed with 2x200 mL CH2Cl2. A total
|
|
of 125 g potassium sodium tartrate was added to the aqueous phase, and
|
|
sufficient 25% NaOH added to bring the pH to about 10. This phase was
|
|
extracted with 3x150 mL CH2Cl2, and the pooled extracts were stripped
|
|
of solvent under vacuum. The residual oil (4.8 g, amber in color) was
|
|
dissolved in 300 mL anhydrous Et2O which, upon saturation with
|
|
anhydrous HCl gas gave a clear solution that suddenly deposited white
|
|
crystals. The hydrochloride salt of
|
|
6-(2-aminopropyl)-5-methoxy-2-methyl-2,3-dihydrobenzofuran weighed 2.3
|
|
g and was not satisfactory as a solid derivative, but it appears that
|
|
the oxalate salt is both nonhygroscopic and quite stable. It (F-2)
|
|
had a mp of 216-218 !C and it displayed a textbook NMR.
|
|
|
|
DOSAGE: greater than 15 mg.
|
|
|
|
DURATION: unknown.
|
|
|
|
EXTENSIONS AND COMMENTARY: This material, which is certainly a mixture
|
|
of two diastereoisomeric pairs of racemates since there are two chiral
|
|
centers present, showed no effects at levels of up to 15 milligrams
|
|
orally. Doses of 100 mg/Kg were without effects in mice following
|
|
i.p. injections, although half again this amount proved to be lethal.
|
|
In rats trained to discriminate LSD from saline, F-2 proved to be
|
|
about 40 times less potent than the reference compound DOM, requiring
|
|
some 5 mg/Kg for positive responses. But the human trials were only
|
|
up to about 0.2 mg/Kg.
|
|
|
|
This was the prototype compound that was originally put together to
|
|
justify giving a paper at a marijuana conference in Sweden, in 1968.
|
|
Although I had never done much with marijuana or with its principal
|
|
ingredients, I thought maybe I could bend the topic a bit to embrace
|
|
some potentially active phenethylamines. There is a story of an
|
|
international conference held in Geneva a few years earlier to discuss
|
|
the worrisome decrease in the elephant population. A German zoologist
|
|
invested a full eight-hour day in a summary of his 21 volume treatise
|
|
on the anatomy and the physiology of the elephant. A French
|
|
sociologist presented a lively slide show on the mating rituals and
|
|
rutting behavior of the elephant. And a rabbi from Tel Aviv entitled
|
|
his talk: RElephants and the Jewish Problem.S My Swedish talk should
|
|
have been named RMarijuana and the Psychedelic Amphetamines.S The
|
|
memorable story of meeting the chief of the Swedish equivalent of the
|
|
Bureau of Narcotics, and ending up playing Mozart sonatas in the attic
|
|
of his home, has been spun out elsewhere in the book.
|
|
|
|
The original concept was a grand plan to imitate two of the three
|
|
rings of tetrahydrocannabinol. There is an aromatic ring (with an
|
|
alkyl group and two oxygens on it) and it is fused to a pyran ring
|
|
with a couple of methyl groups on it. So, if one were to tie the
|
|
methyl group at the 4-position of DOM around with a short carbon chain
|
|
into the oxygen atom at the five position, one could squint and say
|
|
that the resulting amphetamine was kinda something like an analogue of
|
|
THC. Thus, the resulting six-membered ring (a pyran) or five-membered
|
|
ring (a furan) could be peppered with methyl groups at different
|
|
locations (and up to two per location). If the ring was a
|
|
five-membered structure, then the parent system would be a benzofuran,
|
|
and the location of methyl groups on the ring would be indicated by
|
|
the appropriate numbers following the letter RFS which would stand for
|
|
RfuranS. And if it were to be a six-membered ring, the resulting
|
|
benzopyran would be indicated with a RPS for pyran, and again the
|
|
methyl group or groups would be indicated by the substitution
|
|
position. This code would cover all polymethylated homologues with
|
|
codes that would look like F-22 and P-2234. If any of them showed up
|
|
with fascinating activities, I would extend methyls to ethyls, and
|
|
work out some whole new naming code at some future time. An early
|
|
system, naming this compound 2-M for a methyl group on the 2-position
|
|
of the furan ring, was abandoned when it became apparent that the
|
|
pyran world would screw everything up.
|
|
|
|
The isolation of characterizable quantities of
|
|
7-formyl-5-methoxy-2-methyl-2,3-dihydrobenzofuran from the
|
|
benzaldehyde recipe above gave a fleeting fantasy of a whole new
|
|
direction that this little project might go. If this unexpected
|
|
benzaldehyde were to be converted to the corresponding amphetamine,
|
|
one would have
|
|
7-(2-aminopropyl)-5-methoxy-2-methyl-2,3-dihydrobenzofuran. Suddenly
|
|
here would be a 2,3,5-trisubstituted thing with a ring at the
|
|
2,3-position, similar to the still unmade MMDA-4. The temptation to
|
|
be diverted in this way lasted, fortunately, only a few minutes, and
|
|
the project was shelved. Someday, when there are buckets of spare
|
|
time or hosts of eager graduate students, some fascinating chemistry
|
|
might lie this way, and maybe some fascinating pharmacology, even.
|
|
|
|
The plain furan analogue, without any methyl groups on it, has been
|
|
made. Five-methoxybenzofuran formed the 6-formyl derivative (the
|
|
aldehyde) with a mp of 79-80 !C and from it the nitrostyrene (orange
|
|
needles, mp 89-91 !C) and the final amphetamine (white solids, as the
|
|
methane sulfonate, mp 141-144 !C) were prepared in a manner similar to
|
|
the preparation of F-2 above. In the rat studies, it was three times
|
|
more potent than F-2, but still some 15 times less potent than DOM.
|
|
And in initial human trials (of up to 30 milligrams) there were again
|
|
no effects noted. Naming of this material is easy chemically
|
|
(6-(2-aminopropyl)-5-methoxy-2,3-dihydrobenzofuran) but tricky as to
|
|
code. If the numbers that follow the RFS give the location of the
|
|
methyl groups, then this material, without any such groups, can have
|
|
no numbers following, and should properly be simply RF.S OK, it is
|
|
RF.S The preparation or the attempted preparations of other homologues
|
|
such as F-23 and F-233 are outlined under the recipe for F-22.

|
6-(2-AMINOPROPYL)-2,2-DIMETHYL-5-METHOXY-2,3-DIHYDROBENZOFURAN
|
|
|
|
SYNTHESIS: To a solution of 43.2 g flaked KOH in 250 mL hot EtOH there
|
|
was added 96 g 4-methoxyphenol followed by 90 g 2-methylallyl chloride
|
|
over the course of 2 h. The mixture was held at reflux for 24 h, then
|
|
added to 1.6 L H2O. There was sufficient 25% NaOH added to make the
|
|
phase strongly basic, and this was then extracted with 3x200 mL
|
|
CH2Cl2. The pooled extracts were washed with H2O, and the solvent
|
|
removed under vacuum. The residue, 125 g of a pale amber oil, was
|
|
crude 4-(2-methylallyloxy)anisole and was used without further
|
|
purification in the following reaction.
|
|
|
|
In a round-bottomed flask containing an internal thermometer, there
|
|
was placed 125 g of unpurified 4-(2-methylallyloxy)anisole, and this
|
|
was heated with an open flame. At an internal temperature of 190 !C
|
|
an exothermic reaction set in, raising the temperature to 250 !C,
|
|
where it was held for an additional 2 min. After the reaction mixture
|
|
had cooled to room temperature, it was poured into 500 mL H2O, made
|
|
strongly basic with 25% NaOH, and extracted repeatedly with 100 mL
|
|
portions of CH2Cl2 until the extracts were essentially colorless.
|
|
These extracts were pooled and the solvent removed to provide 80.0 g
|
|
of a deeply colored oil that proved to be largely the appropriately
|
|
substituted dihydrobenzofuran. The aqueous residue from above was
|
|
acidified with concentrated HCl, and again extracted with CH2Cl2.
|
|
Removal of the solvent gave 17.7 g of
|
|
4-methoxy-2-(2-methylallyl)phenol as an amber oil which eventually set
|
|
down as white crystals with a mp of 52.5-54 !C.
|
|
|
|
A solution of 17 g of 4-methoxy-2-(2-methylallyl)phenol in 56 g acetic
|
|
acid was treated with 8.4 g zinc chloride followed with 28 mL
|
|
concentrated HCl. This mixture was heated at reflux temperature with
|
|
a mantle for 1 h. After cooling, this was poured into H2O and
|
|
extracted with 2x150 mL CH2Cl2. The pooled extracts were washed with
|
|
several portions of 8% NaOH, until the extracts were colorless. The
|
|
organic fraction was then washed with H2O, and the solvent removed to
|
|
yield 5.8 g of 2,2-dimethyl-5-methoxy-2,3-dihydrobenzofuran as a pale
|
|
amber oil with a pungent smell. This was purified by distillation,
|
|
giving a fraction of an off-white oil with a bp of 136-138 !C at 33
|
|
mm/Hg.
|
|
|
|
To a mixture of 8.0 g N-methylformanilide and 9.2 g POCl3 which had
|
|
been allowed to stand for 0.5 h, there was added 4.0 g
|
|
2,2-dimethyl-5-methoxy-2,3-dihydrobenzofuran, and the mixture held at
|
|
the steam bath temperature for 2.5 h. This was then poured into 200
|
|
mL H2O which produced a black oily phase that gave no hint of
|
|
crystallization. This mixture was extracted with 3x150 mL CH2Cl2 and
|
|
the solvent was removed from the pooled extracts under vacuum. The
|
|
residual oil (which was shown by GC to contain approximately equal
|
|
quantities of two isomeric benzaldehydes A and B) was extracted with
|
|
three 75 mL portions of boiling hexane, each of which on cooling
|
|
deposited a reddish oil that partially crystallized. A fourth hexane
|
|
extract gave nothing more. The solvent was decanted from these three
|
|
extracts, and the semi-solid residues were ground under 3.0 mL MeOH
|
|
giving 1.4 g of pale yellow crystals of
|
|
2,2-dimethyl-6-formyl-5-methoxy-2,3-dihydrobenzo-furan, isomer RBS.
|
|
After recrystallization from MeOH, the color was almost white, and the
|
|
mp was 79.5-80.5 !C. The combined mother liquors were enriched in
|
|
isomer RAS which proved, following preparative GC separation and NMR
|
|
analysis, to be the 7-formyl isomer. The 80 g of impure
|
|
dihydrobenzofuran isolated from the Claisen rearrangement above was
|
|
distilled and a fraction (43.8 g) that boiled from 138-153 !C at 30
|
|
mm/Hg was processed as described here to the aldehyde mixture.
|
|
Following similar hexane extractions, a yield of 4.0 g of a 95% pure
|
|
isomer RBS was finally obtained. The remaining components of this
|
|
fraction were not determined, but it is possible that there were some
|
|
that contained the six-membered benzopyran ring system.
|
|
|
|
To a solution of 5.2 g of
|
|
2,2-dimethyl-6-formyl-5-methoxy-2,3-dihydro-benzofuran in 20 mL
|
|
glacial acetic acid there was added 3 mL nitroethane followed by 1.6 g
|
|
anhydrous ammonium acetate. This mixture was heated for 4 h on the
|
|
steam bath, and then a small amount of H2O was added to the hot
|
|
solution. This instigated the formation of a copious deposition of
|
|
brick-red crystals which were, after cooling, removed by filtration,
|
|
and recrystallized from 50 mL boiling MeOH. After air drying there
|
|
was thus obtained 2.7 g of day-glo yum-yum orange crystals of
|
|
2,2-dimethyl-5-methoxy-6-(2-nitro-1-propenyl)-2,3-dihydrobenzofuran.
|
|
An additional 0.6 g of product was obtained by working the mother
|
|
liquors.
|
|
|
|
A suspension of 2.5 g LAH in 300 mL refluxing anhydrous Et2O was
|
|
treated with a solution of 3.1 g
|
|
2,2-dimethyl-5-methoxy-6-(2-nitro-1-propenyl)-2,3-dihydrobenzofuran in
|
|
Et2O. The mixture was held at reflux temperature for 18 h. After
|
|
cooling, the excess hydride was destroyed by the cautious addition of
|
|
400 mL H2O which contained 15 g H2SO4. The aqueous phase was
|
|
separated, washed once with Et2O, and then once with CH2Cl2. There
|
|
was then added 60 g potassium sodium tartrate, and the pH was brought
|
|
to above 10 by the addition of 25% NaOH. This was extracted with
|
|
3x250 mL CH2Cl2, the extracts pooled, and the solvent removed under
|
|
vacuum. There remained 2.8 g of an amber oil with an ammoniacal
|
|
smell. This was dissolved in 200 mL anhydrous Et2O, and saturated
|
|
with anhydrous HCl gas. There was the immediate formation of an oil,
|
|
from which the supernatent Et2O was decanted. The residual oil was
|
|
resuspended in a second 200 mL anhydrous Et2O, again decanted, and
|
|
finally a third 200 mL Et2O effected the dissolving of the remaining
|
|
oil to give a clear solution. All three solutions became gelatinous
|
|
over the following few h, and each deposited a crop of white crystals
|
|
over the following few days. From the first there was obtained 1.4 g
|
|
of product with a mp of 153-154 !C; from the second, 0.2 g with a mp
|
|
of 153-154 !C; and from the third, 1.2 g with a mp of 155-156 !C.
|
|
These crops were combined, and recrystallized from 10 mL of boiling
|
|
CH3CN to give 1.7 g

|
6-(2-aminopropyl)-2,2-dimethyl-5-methoxy-2,3-dihydrobenzofuran
|
|
hydrochloride (F-22) as a white crystalline solid which had a mp of
|
|
154-155 !C. This material, even when dry, showed a tendency to
|
|
discolor with time.
|
|
|
|
DOSAGE: greater than 15 mg.
|
|
|
|
DURATION: unknown.
|
|
|
|
EXTENSIONS AND COMMENTARY: And here is yet another dihydrobenzofuran
|
|
which is not of a very high potency if, indeed, it is active at all.
|
|
This particular dihydrobenzofuran analogue, F-22, had sort of tickled
|
|
my fancy as being an especially good candidate for activity. It had a
|
|
certain swing to it. F-22, like LSD-25. And here it was finished,
|
|
just five days before I had to deliver a paper concerning the
|
|
syntheses (and activities!) of all these dihydrobenzofurans to the
|
|
marijuana congress. Could this possibly be another LSD? I was
|
|
sufficiently convinced that the possibility was real, that I actually
|
|
started the screening process at a most unusually low level of 10
|
|
micrograms. Two days later, I upped this to a dose of 25 micrograms
|
|
(no activity again) and three days after that, at 1 AM on the polar
|
|
flight to Copenhagen, I swallowed the RmonstrousS dose of 50
|
|
micrograms. Shoot the works. If I were to blossom all over the
|
|
tourist section of the SAS plane, well, it would be quite a paper to
|
|
give. If not, I could always say something like, RThe active level
|
|
has not yet been found.S No activity. Another Walter Mitty fantasy
|
|
down the tubes.
|
|
|
|
And, as it turned out, the entire project pretty much ran out of
|
|
steam. A number of clever analogs had been started, and would have
|
|
been pursued if there had been any activity promised of any kind with
|
|
any of these dihydrobenzofurans. The RotherS benzaldehyde described
|
|
above, could have been run in a manner parallel to that proposed for
|
|
the counterpart with F-2, to make the eventual amphetamine,
|
|
7-(2-aminopropyl)-2,2-dimethyl-5-methoxy-2,3-dihydrobenzofuran. Great
|
|
strides had been made towards F-233 (I have discussed the naming
|
|
system under F-2, with the F standing for the furan of benzofuran and
|
|
the 2 and 3 and 3 being the positions of the methyl groups on it).
|
|
The reaction of 4-methoxyphenol with 1-chloro-3-methyl-2-butene gave
|
|
the ether which underwent the thermal Claisen rearrangement to
|
|
2-(1,1-dimethylallyl)-4-methoxyphenol with a bp of 148-157 !C at 30
|
|
mm/Hg. This was cyclized to the intermediate cycle
|
|
2,3,3-trimethyl-2,3-dihydrobenzofuran which, after distillation, was
|
|
shown to be only 80% pure by GC analysis. This was, nonetheless, (and
|
|
with the hope that is in the very fiber of a young innocent chemist),
|
|
pushed on to the benzaldehyde stage (and there were a
|
|
not-too-surprising four benzaldehydes to be found in the oil that was
|
|
produced, which refused to crystallize). And then (when sheer
|
|
desperation replaced hope) these were condensed with nitroethane to
|
|
form an even worse mixture. Maybe something might crystallize from
|
|
it? Nothing ever did. Junk. Everything was simply put on the shelf
|
|
where it still rests today, and F-233,
|
|
6-(2-aminopropyl)-5-methoxy-2,3,3-trimethyl-2,3-dihydrobenzofuran,
|
|
remains the stuff of speculation.
|
|
|
|
And a start towards F-23,
|
|
6-(2-aminopropyl)-2,3-dimethyl-5-methoxy-2,3-dihydrobenzofuran, got
|
|
just as far as the starting ether, when it occurred to me that the
|
|
final product would have an unprecedented three chiral centers, and so
|
|
a total of four racemic pairs of diastereoisomers. And then I
|
|
discovered that the starting allyl halide, crotyl chloride, was only
|
|
80% pure, with the remaining 20% being 3-chloro-1-butene. This would
|
|
have eventually produced a 2-ethyl-analogue,
|
|
6-(2-aminopropyl)-2-ethyl-5-methoxy-2,3-dihydrobenzofuran, with its
|
|
two chiral centers and two more pairs of stereoisomers (not to speak
|
|
of the need to devise an entirely new coding system). Unless
|
|
something were to fall into my lap as a crystalline intermediate, the
|
|
final mess could have had at least six discreet compounds in it, not
|
|
even considering optical isomers. And I havenUt even begun to think
|
|
of making the six-membered dihydrobenzopyrans which were the THC
|
|
analogues that presented the rationale that started the whole project
|
|
in the first place. A recent issue of the Journal of Medicinal
|
|
Chemistry has just presented an article describing the reaction of
|
|
6-methoxytetrahydrobenzopyran with dichloromethyl methyl ether, and
|
|
approximately equal amounts of all three of the possible isomers were
|
|
obtained. That would have been the first step towards making the
|
|
prototypic compound 7-(2-aminopropyl)
|
|
6-methoxy-1,2,3,4-tetrahydrobenzopyran. Just as the benzofurans were
|
|
all named as F-compounds, this, as a benzopyran, would have been a P
|
|
compound, but P also is used for proscaline, and there would have been
|
|
some repair-work needed for these codes.
|
|
|
|
Time to abandon ship. The fact that I had just synthesized and
|
|
discovered the strange activity of ARIADNE at about this time, made
|
|
the ship abandonment quite a bit easier to accept.

#81 FLEA; N-HYDROXY-N-METHYL-3,4-METHYLENEDIOXYAMPHETAMINE
|
|
|
|
SYNTHESIS: (from 3,4-methylenedioxyphenylacetone) A solution of 2.1 g
|
|
N-methylhydroxylamine hydrochloride and 4.4 g
|
|
3,4-methylenedioxyphenylacetone in 5.5 mL MeOH was added to a
|
|
suspension of 4.5 g NaHCO3 in 30 mL boiling MeOH. There was added
|
|
about 5 mL H2O (which gave a clear solution) followed by another 50 mL
|
|
H2O which produced a pale yellow color. To this solution of the
|
|
unisolated nitrone there was added 1.7 g sodium cyanoborohydride,
|
|
which generated a goodly amount of foaming. There was HCl added as
|
|
needed to maintain the pH at about neutrality. The reaction appeared
|
|
to have stopped after a day or two, so all was poured into 500 mL H2O,
|
|
acidified with HCl, and washed with 2x75 mL CH2Cl2. The addition of
|
|
base brought the pH >9, and this was then extracted with 3x75 mL
|
|
CH2Cl2. Removal of the solvent from the pooled extracts gave a
|
|
residue of 1.65 g of crude
|
|
N-hydroxy-N-methyl-3,4-methylenedioxyamphetamine. Efforts to obtain
|
|
solid seed samples of the salts with hydrochloric acid, perchloric
|
|
acid, sulfuric acid, phosphoric acid, and with a number of organic
|
|
acids, all failed. The salt formation from this free-base will be
|
|
discussed below.
|
|
|
|
(from MDOH) A solution of 0.75 g crystalline free-base MDOH in a few
|
|
mL MeOH was treated with a solution of 0.4 g sodium cyanoborohydride
|
|
in 10 mL MeOH, and there was then added 2 mL of 35% formaldehyde. The
|
|
stirred reaction mixture was kept at a neutral pH with the occasional
|
|
addition of HCl. After several days (when additional acid was no
|
|
longer required) the excess solvent was removed under vacuum, and the
|
|
residue poured into dilute H2SO4. This was washed with 2x75 mL CH2Cl2
|
|
and then, following the addition of base, this was extracted with 3x75
|
|
mL CH2Cl2. Removal of the solvent from the pooled extracts gave a
|
|
viscous oil residue of 0.53 g. The free-base product from these
|
|
preparations was distilled at 110-120 !C at 0.2 mm/Hg to give the
|
|
N-hydroxy-N-methyl product as a white oil. An alternate methylation
|
|
procedure used a solution of MDOH in a 4:1 MeOH/acetic acid solution
|
|
containing formaldehyde which was reduced with sodium borohydride at
|
|
dry ice temperatures. Its work-up is identical to that involving
|
|
sodium cyanoborohydride.
|
|
|
|
The distilled product was dissolved in an equal volume of MeOH, and
|
|
treated with a half-equivalent of oxalic acid dihydrate, dissolved in
|
|
10 volumes of MeOH. This combination gave the slow deposition of
|
|
crystals of the full oxalate salt (one acid, two bases) as a white
|
|
crystalline product. The mp of the crude salt was in the 130-150 !C
|
|
range, and after recrystallization from CH3CN,
|
|
N-hydroxy-N-methyl-3,4-methylenedioxyamphetamine oxalate (FLEA) had a
|
|
mp of 146-147 !C.
|
|
|
|
DOSAGE: 100 - 160 mg.
|
|
|
|
DURATION: 4 - 8 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 90 mg) The material tastes terrible, like
|
|
grapefruit juice that has stayed in the can too long. There was no
|
|
nausea, no feeling of difficulty in swallowing at any time during the
|
|
day. I felt a dry mouth and was thirsty Q sipped water throughout the
|
|
day. At the beginning of the experiment, there was a glimmer of the
|
|
MDMA warmth, but later I felt separated and a bit isolated. I was
|
|
just floating around, seeing the beauty of colors and objects in the
|
|
house and outdoors and listening first to this conversation, then to
|
|
that one. All senses seemed enhanced. I found the material pleasant.
|
|
I was happy with the amount I took but would not be afraid to take
|
|
more or to take a supplement. I found it similar to, but not the same
|
|
as, MDMA.
|
|
|
|
(with 110 mg) We found this very similar to MDMA, but perhaps
|
|
slightly slower. I plateauUd at 2:30 hours and had a very gradual
|
|
descent. My friend had a marvelous and private 'cone of silence' that
|
|
was to him unique to MDMA or to 2C-T-8. Teeth problems were minor,
|
|
and the descent from the top of the experience showed less
|
|
interactive, and more contemplative action, than with MDMA. Very
|
|
similar to MDMA, but with its own character.
|
|
|
|
(with 110 mg) The onset was at about a half-hour. The come-on was
|
|
more gradual and much easier than with MDMA, and it seemed to be more
|
|
head than body oriented. I had about two hours of very complex and
|
|
personal self-evaluation, and I am not at peace in putting all of it
|
|
down here in writing. Overall I like it, and I would be interested to
|
|
see if there's a difference in conjunction with MDMA. Thanks very
|
|
much.
|
|
|
|
(with 110 mg + 35 mg) I saw my onset at 20 minutes, and it was
|
|
subtle, and very pleasant, and had a mild amphetamine-like elevation
|
|
for me (body lightness, cognitive functions seemed clear and clean,
|
|
heightened visual awareness and with some enhancement of color). It
|
|
seemed as if I were on the fringe of LSD-like visual changes, but that
|
|
never materialized. The affect was very good, communicative,
|
|
friendly, accepting, but without the profound emotional bonding of
|
|
MDMA. The following day felt very much like a post-LSD day; we felt
|
|
great. The body was light, energy good, emotions high, several
|
|
insights throughout the day, interactions clear and open Q a
|
|
magnificent gift of a day. I started a menstrual period the day of
|
|
the experience and it lasted 6 to 7 days; all of this was a couple of
|
|
weeks early. I have a very favorable impression of FLEA although the
|
|
body penalty seems high.
|
|
|
|
EXTENSIONS AND COMMENTARY: Most people who were involved with the
|
|
evaluation of FLEA quite logically compared it with MDMA, as it was
|
|
presented as being a very close analogue which might share some of the
|
|
latter's properties. And to a large measure, the comparison was
|
|
favorable. The dosages are almost identical, the chronological course
|
|
of action is almost identical, and there are distinct similarities in
|
|
the effects that are produced. If there is a consensus of
|
|
similarities and differences it would be that it is not quite as
|
|
enabling in allowing a closeness to be established with others. And
|
|
perhaps there is more of a move towards introspection. And perhaps a
|
|
slightly increased degree of discoordination in the thought processes.
|
|
But also, part of this same consensus was that, were MDMA unknown,
|
|
this material would have played its role completely.
|
|
|
|
And from the scientific point of view, it lends more weight to a
|
|
hypothesis that just might be a tremendous research tool in
|
|
pharmacology. I first observed the intimate connection between an
|
|
amine and a hydroxylamine with the discovery that N-hydroxy-MDA (MDOH)
|
|
was equipotent and of virtually identical activity to the
|
|
non-hydroxylated counterpart (MDA). And I have speculated in the
|
|
recipe for MDOH about the possible biological interconversions of
|
|
these kinds of compounds. And here, the simple addition of a hydroxyl
|
|
group to the amine nitrogen atom of MDMA produces a new drug that is
|
|
in most of its properties identical to MDMA. The concept has been
|
|
extended to 2C-T-2, 2C-T-7, and 2C-T-17, where each of these three
|
|
active compounds was structurally modified in exactly this way, by the
|
|
addition of a hydroxyl group to the amine nitrogen atom. The results,
|
|
HOT-2, HOT-7 and HOT-17 were themselves all active, and compared very
|
|
closely with their non-hydroxylated prototypes.
|
|
|
|
Just how general might this concept be, that an N-hydroxyl analog of
|
|
an active amine shall be of similar action and duration as the parent
|
|
drug? What if it really were a generality! What havoc it would wreak
|
|
in the pharmaceutical industry! If I could patent the concept, then I
|
|
would be able to make parallel best sellers to all of the primary and
|
|
secondary amines out there in the industry. Perhaps 90% of all the
|
|
commercially available drugs that are concerned with the human mental
|
|
state are amines. And a goodly number of these are primary or
|
|
secondary amines. And each and every one of these could be converted
|
|
to its N-hydroxyl analogue, effectively by-passing the patent
|
|
protection that the originating corporation so carefully crafted. An
|
|
example, just for fun. A run-away best seller right now is an
|
|
antidepressant called fluoxetine, with the trade name Prozac. I will
|
|
make a small wager that if I were to synthesize and taste
|
|
N-hydroxy-N-methyl-3-phenyl-3-((a,a,a-trifluoro-p-tolyl)oxy)propylamine,
|
|
I would find it to be an active antidepressant. Remember, Mr. Eli
|
|
Lilly and Company; you read about it first, right here!
|
|
|
|
Of course, I was asked, why call it FLEA? The origin was in a classic
|
|
bit of poetry. A commonly used code name for MDMA was ADAM, and I had
|
|
tried making several modest modifications of the MDMA structure in the
|
|
search for another compound that would maintain its particular music
|
|
without the annoying tooth-grinding and occasional nystagmus, or
|
|
eye-wiggle, that some users have mentioned. One of these was the
|
|
6-methyl homologue which was, with some perverse logic, called MADAM.
|
|
And, following this pattern, the 6-fluoroanalogue was to be FLADAM.
|
|
So, with the N-hydroxy analogue, what about HADAM? Which brought to
|
|
mind the classic description of Adam's earliest complaint, an
|
|
infestation of fleas. The poem was short and direct. RAdam had Uem.
|
|
So, in place of HAD UEM, the term FLEA jumped into being.

#82 G-3; 2,5-DIMETHOXY-3,4-(TRIMETHYLENE)AMPHETAMINE;
|
|
|
|
5-(2-AMINOPROPYL)-4,7-DIMETHOXYINDANE
|
|
|
|
SYNTHESIS: A solution of 3.7 g of
|
|
2,5-dimethoxy-3,4-(trimethylene)benzaldehyde (see preparation under
|
|
2C-G-3) in 15 mL nitroethane was treated with 0.7 g anhydrous ammonium
|
|
acetate and heated on the steam bath for 2.5 h. The excess solvent
|
|
was removed under vacuum leaving some 5 mL of a deep orange-red oil
|
|
which on cooling, spontaneously crystallized. This was finely ground
|
|
under 10 mL MeOH, filtered, washed sparingly with MeOH, and air dried
|
|
to give 3.6 g of orange crystals with a strong smell of old acetamide.
|
|
The mp was 92-93 !C. All was recrystallized from 30 mL boiling MeOH
|
|
to give, after filtering and drying, 2.9 g of
|
|
1-(2,5-dimethoxy-3,4-(trimethylene)phenyl)-2-nitropropene as yellow
|
|
crystals with a mp of 93-94 !C. Anal. (C14H17NO4) C,H,N.
|
|
|
|
Fifty milliliters of 1 M LAH in THF was placed in an inert atmosphere,
|
|
well stirred, and cooled to 0 !C with an external ice-bath. There was
|
|
added, dropwise, 1.35 mL of 100% H2SO4 at a rate slow enough to
|
|
minimize charring. There was then added, dropwise, 2.8 g
|
|
1-(2,5-dimethoxy-3,4-(trimethylene)phenyl)-2-nitropropene in 15 mL
|
|
THF. At the end of the addition, the stirring was continued for an
|
|
additional 0.5 h, and then the reaction mixture was held at reflux on
|
|
the steam bath for another 0.5 h. After cooling again to ice-bath
|
|
temperature, the excess hydride was destroyed with the addition of 11
|
|
mL IPA, followed by 5.5 mL 5% NaOH which converted the inorganic mass
|
|
through a cottage cheese stage into a loose, filterable texture. The
|
|
solids were removed by filtration, washed with additional THF, and the
|
|
combined filtrates and washes stripped of solvent under vacuum. There
|
|
was obtained 2.51 g of a white oil that was distilled at 115-135 !C at
|
|
0.2 mm/Hg to give 1.83 g of a clear colorless oil. This was dissolved
|
|
in 8 mL IPA, neutralized with 28 drops of concentrated HCl, and
|
|
diluted with 140 mL anhydrous Et2O. In about 0.5 h there started a
|
|
slow snowfall of fine fluffy white crystals which was allowed to
|
|
continue until no additional crystals appeared. After filtering, Et2O
|
|
washing and air drying, there was obtained 1.81 g of
|
|
2,5-dimethoxy-3,4-(trimethylene)amphetamine hydrochloride (G-3) with a
|
|
mp of 157-159 !C. Anal. (C14H22ClNO2) C,H.
|
|
|
|
DOSAGE: 12 - 18 mg.
|
|
|
|
DURATION: 8 - 12 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 12 mg) There was a warmth, a mellowness,
|
|
as things developed. No body disturbance at all, but then there were
|
|
no visuals either which, for me on this particular occasion, was
|
|
disappointing. The day was consumed in reading, and I identified
|
|
completely with the character of my fictional hero. It was a
|
|
different form of fantasy. I think I prefer music as a structural
|
|
basis for fantasy.
|
|
|
|
(with 18 mg) I am at a plus three, but I am not at all sure of why it
|
|
is a plus three. With my eyes closed, there are puffy clouds, but no
|
|
drama at all. Music was not exciting. There could well have been
|
|
easy eroticism, but there was no push in that direction. No great
|
|
amount of appetite. Not much of anything, and still a plus three.
|
|
Simply lying still and surveying the body rather than the visual scene
|
|
gave some suggestions of neurological sensitivity, but with getting up
|
|
and moving about and doing things, all was fine. The next morning I
|
|
was perhaps moving a bit more slowly than usual. I am not sure that
|
|
there would be reward in going higher.
|
|
|
|
EXTENSIONS AND COMMENTARY: In a comparison between the 2-carbon
|
|
compound (2C-G-3) and the 3-carbon compound (G-3) the vote goes
|
|
towards the phenethylamine (the 2-carbon compound). With the first
|
|
member of this series (2C-G versus GANESHA) this was a stand-off, both
|
|
as to quantitative effects (potency) and qualitative effects (nature
|
|
of activity). Here, with the somewhat bulkier group located at the
|
|
definitive 3,4-positions, the nod is to the shorter chain, for the
|
|
first time ever. The potency differences are small, and maybe the
|
|
amphetamine is still a bit more potent. But there are hints of
|
|
discomfort with this latter compound that seem to be absent with the
|
|
phenethylamine. The more highly substituted compounds (q.v.) more
|
|
clearly define these differences.

#83 G-4; 2,5-DIMETHOXY-3,4-(TETRAMETHYLENE)AMPHETAMINE;
|
|
6-(2-AMINOPROPYL)-5,8-DIMETHOXYTETRALIN
|
|
|
|
SYNTHESIS: A solution of
|
|
1,4-dimethoxy-5,6,7,8-tetrahydro-'-naphthaldehyde (see preparation
|
|
under 2C-G-4) in 20 mL nitroethane was treated with 0.13 g anhydrous
|
|
ammonium acetate and heated on the steam bath overnight. The
|
|
volatiles were removed under vacuum and the residue, on cooling,
|
|
spontaneously crystallized. This crude rust-colored product (1.98 g)
|
|
was recrystallized from 15 mL boiling MeOH yielding, after filtering
|
|
and air drying to constant weight, 1.33 g of
|
|
1-(2,5-dimethoxy-3,4-(tetramethylene)phenyl)-2-nitropropene as dull
|
|
gold-colored crystals. The mp was 94-94.5 !C. Anal. (C15H19NO4) C,H.
|
|
|
|
DOSAGE: unknown.
|
|
|
|
DURATION: unknown.
|
|
|
|
EXTENSIONS AND COMMENTARY: The discussion that appeared in the
|
|
commentary section under 2C-G-4 applies here as well. The major
|
|
struggles were in the preparation of the aldehyde itself. And
|
|
although the final product has not yet been made, this last synthetic
|
|
step should be, as Bobby Fischer once said in his analysis of a
|
|
master's chess game following a blunder by his opponent, simply a
|
|
matter of technique.
|
|
|
|
As with the phenethylamine counterpart, G-4 has a structure that lies
|
|
intermediate between G-3 and G-5, both potent compounds. It is
|
|
axiomatic that it too will be a potent thing, and all that now needs
|
|
be done is to complete its synthesis and taste it.

#84 G-5; 3,6-DIMETHOXY-4-(2-AMINOPROPYL)BENZONORBORNANE
|
|
|
|
SYNTHESIS: A solution of 3.70 g 3,6-dimethoxy-4-formylbenzonorbornane
|
|
(see under 2C-G-5 for its preparation) in 20 g nitroethane was treated
|
|
with 0.88 g anhydrous ammonium acetate and held at steam bath
|
|
temperature overnight. The excess solvent and reagent was removed
|
|
under vacuum to yield a residual yellow oil. This was allowed to
|
|
stand at ambient temperature for a period of time (about 3 years) by
|
|
which time there was a spontaneous crystallization. The dull yellow
|
|
crystals were removed by filtration and, after air drying, weighed
|
|
4.28 g. A small sample was recrystallized repeatedly from MeOH to
|
|
provide a pale yellow analytical sample of

|
!C. Anal. (C16H19NO4) C,H.
|
|
|
|
A solution of LAH (50 mL of 1 M solution in THF) was cooled, under He,
|
|
to 0 !C with an external ice bath. With good stirring there was added
|
|
1.32 mL 100% H2SO4 dropwise, to minimize charring. This was followed
|
|
by the addition of 4.1 g
|
|
3,6-dimethoxy-4-(2-nitropropenyl)benzonorbornane in 20 mL anhydrous
|
|
THF over the course of 10 min. The reaction mixture was stirred and
|
|
brought to room temperature over the course of 1 h. This was then
|
|
brought to a gentle reflux on the steam bath for 0.5 h, and then all
|
|
was cooled again to 0 !C. The excess hydride was destroyed by the
|
|
cautious addition of 10 mL IPA followed by 5 mL 5% NaOH and sufficient
|
|
H2O to give a white granular character to the oxides. The reaction
|
|
mixture was filtered, and the filter cake washed with THF. The
|
|
filtrate was stripped of solvent under vacuum providing a pale amber
|
|
oil that was distilled at 125-140 !C at 0.2 mm/Hg to give 2.5 g of an
|
|
almost white oil. This was dissolved in 10 mL IPA, neutralized with
|
|
25 drops of concentrated HCl, and then diluted with 140 mL anhydrous
|
|
Et2O. There appeared, after about two minutes, white crystals of
|
|
3,6-dimethoxy-4-(2-aminopropyl)benzonorbornane hydrochloride (G-5)
|
|
which, after filtration and air drying, weighed 2.47 g.
|
|
|
|
DOSAGE: 14 - 20 mg.
|
|
|
|
DURATION: 16 - 30 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 15 mg) As part of the audience at the San
|
|
Francisco conference, Angels, Aliens and Archtypes, I could simply
|
|
listen and observe without having to participate. Each speaker stood
|
|
in a cone of light that was beautifully bright and colorful, casting
|
|
everything else on the stage into obscurity. Maybe angels really are
|
|
illuminated from above, and the aliens lurk out of sight until it is
|
|
their turn. Where does one look for the archetypes? A half of a
|
|
cream cheese sandwich was all I could eat, and even at dinner that
|
|
evening I was not hungry. Sleep that evening was difficult.
|
|
|
|
(with 20 mg) Very slow to come on, but then it was up there all of a
|
|
sudden. There is an unexpected absence of visual activity despite
|
|
being at a full +++. The mental activity is excellent, with easy
|
|
writing and a positive flow of ideas. But an absence of the bells and
|
|
whistles that are expected with a psychedelic in full bloom. There is
|
|
a real drop by the 16th hour and the next day was free of effect
|
|
except for occasional cat-naps.
|
|
|
|
(with 20 mg) The transition period, which usually lasts for most
|
|
compounds for the first hour or two, with this seems to be much
|
|
longer. This presages a long-acting material, as usually the slow-in
|
|
slow-out rule applies. But there are exceptions. There is an
|
|
indifference towards the erotic, but no separation at all from
|
|
personal interactions and emotions. I believe in integration, not
|
|
separation of all parts of ourselves, distrusting any drug states
|
|
(particularly those that have the reputation of being strongly
|
|
Tcosmic)U which divorce the consciousness from the body. And with
|
|
this material there is no separation from feelings, only from my
|
|
particular color language.
|
|
|
|
EXTENSIONS AND COMMENTARY: This is as potent as any of the
|
|
three-carbon Ganesha compounds, but it somehow lacks a little
|
|
something that would have made it a completely favorite winner.
|
|
Perhaps it is the generally commented upon absence of visual and
|
|
related sensory entertainment. There seems to be no bodily threat to
|
|
discourage further exploration, but there simply was not the drive to
|
|
explore it much. The comments concerning the enlargement of the ring
|
|
system (mentioned under 2C-G-5) are equally valid here. The
|
|
RshrubberyS that is the hallmark of the Ganesha family is, with G-5,
|
|
about as bulky as has ever been put onto a centrally active molecule.
|
|
The norbornane group has a one carbon bridge and a two carbon bridge
|
|
sticking out of it at odd angles. The replacement of the one-carbon
|
|
bridge with a second two-carbon bridge would make the compound G-6.
|
|
It would be makeable, but is there really a driving reason to do so?
|
|
There is a simplification intrinsic in this, in that G-5 actually has
|
|
two centers of asymmetry (the a-carbon atom on the amphetamine chain,
|
|
and the norbornyl area itself) and so it is really a mixture of two
|
|
racemic diastereoisomers. G-6 would still be a racemate, but it would
|
|
be only a single compound, as are all the other substituted
|
|
amphetamine derivatives.
|
|
|
|
Someday I may try making G-6, but it's not a high priority right now.

#85 GANESHA; G; 2,5-DIMETHOXY-3,4-DIMETHYLAMPHETAMINE
|
|
|
|
SYNTHESIS: A solution of 15.4 g 2,5-dimethoxy-3,4-dimethylbenzaldehyde
|
|
(see under 2C-G for the preparation) in 50 mL nitroethane was treated
|
|
with 3 g anhydrous ammonium acetate and heated on the steam bath for
|
|
12 h. The excess nitroethane was removed under vacuum, and the
|
|
residual oil was diluted with a equal volume of MeOH. There was the
|
|
slow generation of deep red cottage-cheese-like crystals which were
|
|
removed by filtration and air-dried to constant weight (9.3 g) with a
|
|
mp 71-74 !C. Recrystal-lization from MeOH (10 ml/g) gave an
|
|
analytical sample of
|
|
1-(2,5-dimethoxy-3,4-dimethylphenyl)-2-nitropropene with a mp of 82 !C
|
|
sharp. Anal. (C13H17NO4) C,H,N. The NMR spectra (in CDCl3) and CI
|
|
mass spectrograph (MH+ = 252) were proper.
|
|
|
|
To a suspension of 3.3 g LAH in 200 mL refluxing THF, well stirred and
|
|
maintained under an inert atmosphere, there was added 4.2 g
|
|
1-(2,5-dimethoxy-3,4-dimethylphenyl)-2-nitropropene in 25 mL THF. The
|
|
mixture was held at reflux for 48 h. After cooling, 3.3 mL H2O was
|
|
added cautiously to decompose the excess hydride, followed by 3.3 mL
|
|
15% NaOH and finally another 10 mL H2O. The inorganic solids were
|
|
removed by filtration, and washed with additional THF. The combined
|
|
filtrate and washes were stripped of solvent under vacuum, and the
|
|
residue (4.7 g of a deep amber oil) dissolved in dilute HCl. This was
|
|
washed with CH2Cl2 (3x75 mL), then made basic with 5% NaOH and
|
|
extracted with CH2Cl2. Removal of the solvent under vacuum yielded an
|
|
amber oil that was distilled (105-115 !C at 0.4 mm/Hg) to give 1.2 g
|
|
of a white oil. This was dissolved in 8 mL IPA, neutralized with 15
|
|
drops of concentrated HCl, and diluted with 250 mL anhydrous Et2O.
|
|
After a period of time, there was a spontaneous appearance of white
|
|
crystals which were removed by filtration, Et2O washed, and air dried.
|
|
Thus was obtained 1.0 g of 2,5-dimethoxy-3,4-dimethylamphetamine
|
|
hydrochloride (GANESHA) with a mp of 168-169 !C. This was not
|
|
improved by recrystallization from either EtOAc or nitroethane. Anal.
|
|
(C13H22ClNO2) N.
|
|
|
|
DOSAGE: 20 - 32 mg.
|
|
|
|
DURATION: 18 - 24 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 24 mg) There was a slow buildup to a ++
|
|
or more over the course of about three hours. Extremely tranquil, and
|
|
no hint of any body toxicity whatsoever. More than tranquil, I was
|
|
completely at peace, in a beautiful, benign, and placid place. There
|
|
was something residual that extended into the sleep period, and was
|
|
possibly still there in the morning. Probably I was simply tired from
|
|
an inadequate sleep.
|
|
|
|
(with 32 mg) A rapid and full development. Lying down with music,
|
|
the eyes-closed visuals were quite something. There was sudden
|
|
awareness of a potential toe cramp which I possibly exaggerated, but
|
|
it kept spinning itself into my awareness, and somehow locked in with
|
|
my visual imagery. It was not easy to keep the visual/somatic/
|
|
cognitive worlds in their proper places. The almost-cramp went away
|
|
and I forgot about it. There was a back spasm somewhere in this
|
|
drama, and it really didnUt matter either. This dosage may be a bit
|
|
much for good housekeeping, though! Towards the end of the
|
|
experiment, I looked at a collection of photos from a recent trip to
|
|
Europe, and the visual enhancement was wonderful. A rolling +++.
|
|
|
|
EXTENSIONS AND COMMENTARY: This compound was the seventh of the ten
|
|
possible Classic Ladies. I have mentioned the concept already under
|
|
the discussions on ARIADNE. This is the teutonic replacement of each
|
|
of the distinguishable hydrogen atoms of DOM with a methyl group. The
|
|
findings with GANESHA were a total surprise. The extension of a
|
|
hydrogen in the 3-position of DOM with a methyl group should have a
|
|
minor influence on its steric association with whatever receptor site
|
|
might be involved. A much greater impact might come not from the size
|
|
of the group but from its location. This, coupled with a full order
|
|
of magnitude of decrease in potency, seemed to call for an involvement
|
|
of that particular position as being one that is affected by
|
|
metabolism. And since the activity is decreased, the obvious role is
|
|
in the blocking of the metabolic promotion of DOM-like things to
|
|
active intermediates.
|
|
|
|
The remarkable point being emphasized here is that the placement of a
|
|
dull methyl group at a dull position of the DOM molecule actually
|
|
inactivated (for all intents and purposes) the activity of DOM. It is
|
|
not the presence of the methyl that has decimated the potency, but the
|
|
removal of the hydrogen atom.
|
|
|
|
How can such a hypothesis be explored? A historic premise of the
|
|
medicinal chemist is that if a structure gives an unusual response in
|
|
a receptor, vary it slightly and see how the response varies. This is
|
|
exactly the principle that led to the ten Classic Ladies, and with
|
|
this particular Lady (who actually turned out to be a gentleman), the
|
|
same concept should hold. There are two involved methyl groups in
|
|
GANESHA, one at the 3-position and one at the 4-position. Why not
|
|
homologate each to an ethyl group, and as a wrap up make both of them
|
|
into ethyl groups. Look at the differences along two lines of
|
|
variation; the effects of the homologation of the 3- and 4-positions,
|
|
coupled with the effects of the homologation intrinsic in the
|
|
comparison of the two-carbon chain of the phenethylamine with the
|
|
three-carbon chain of the amphetamine.
|
|
|
|
There are thus six compounds involved in such a study. And they have
|
|
been named (as have all the other GANESHA analogues) in accordance
|
|
with the collective carbon inventory in and about these two ring
|
|
positions. The first two compounds are related to DOET and to 2C-E.
|
|
Maintain the methyl group at the 3-position but homologate the
|
|
4-position to an ethyl. The ring pattern would become
|
|
2,5-dimethoxy-4-ethyl-3-methyl, and the phenethylamine and amphetamine
|
|
would be called 2C-G-12 and G-12 respectively (a one carbon thing, the
|
|
methyl, at position-3 and a two carbon thing, an ethyl, at
|
|
position-4). Reversal of these groups, the 3-ethyl homologues of 2C-D
|
|
and DOM would thus become 2C-G-21 and G-21. And, finally, the diethyl
|
|
homologues would be 2C-G-22 and G-22. In each of these cases, the
|
|
paired numbers give the lengths of the chains at the two positions,
|
|
the 3- and the 4-positions that are part of the GANESHA concept. And
|
|
this code is easily expandable to longer things such as 2C-G-31 and
|
|
2C-G-41, which would be the 3-propyl-4-methyl, and the
|
|
3-butyl-4-methyl homologues, resp.
|
|
|
|
Unfortunately, these six initially proposed compounds have so far
|
|
resisted all logical approaches to synthesis, and are at present still
|
|
unknown. What has been successfully achieved, the building up of a
|
|
big bulky hydrocarbon glob at these positions, has rather unexpectedly
|
|
led to a remarkable enhancement of potency. As with all true
|
|
exploration into areas of the unknown, the deeper you get, the less
|
|
you understand.

#86 G-N; 1,4-DIMETHOXYNAPHTHYL-2-ISOPROPYLAMINE
|
|
|
|
SYNTHESIS: To a solution of 3.9 g 1,4-dimethoxy-2-naphthaldehyde (see
|
|
under 2C-G-N for the preparation) in 13.5 mL nitroethane there was
|
|
added 0.7 g anhydrous ammonium acetate, and the mixture heated on the
|
|
steam bath for 5 h. The deep orange reaction mixture was stripped of
|
|
excess solvent under vacuum. The residue was a red oil that, upon
|
|
dilution with two volumes MeOH, immediately set to orange crystals.
|
|
This crude product (mp 115-118 !C) was recrystallized from 70 mL EtOH
|
|
to yield, after filtering and air drying, 3.3 g of
|
|
1-(1,4-dimethoxy-2-naphthyl)-2-nitropropene as gold-orange crystals,
|
|
with a mp of 121-123 !C. Recrystallization from MeOH gave a
|
|
gold-colored product with a mp of 119-120 !C. Anal. (C15H15NO4)
|
|
C,H,N.
|
|
|
|
A solution of LAH (50 mL of 1 M solution in THF) was cooled, under He,
|
|
to 0 !C with an external ice-bath. With good stirring there was added
|
|
1.32 mL 100% H2SO4 dropwise, to minimize charring. This was followed
|
|
by the addition of 3.12 g 1-(1,4-dimethoxy-2-naphthyl)-2-nitropropene
|
|
in 40 mL anhydrous THF. After stirring for 1 h, the temperature was
|
|
brought up to a gentle reflux on the steam bath for 0.5 h, and then
|
|
all was cooled again to 0 !C. The excess hydride was destroyed by the
|
|
cautious addition of 16 mL IPA followed by 6 mL 5% NaOH to give a
|
|
white, filterable, granular character to the oxides, and to assure
|
|
that the reaction mixture was basic. The reaction mixture was
|
|
filtered, and the filter cake washed with additional THF. The
|
|
combined filtrate and washes were stripped of solvent under vacuum
|
|
providing 3.17 g of a deep amber oil. Without any further
|
|
purification, this was distilled at 140-160 !C at 0.3 mm/Hg to give
|
|
1.25 g of a pale yellow oil. This was dissolved in 8 mL IPA,
|
|
neutralized with 20 drops of concentrated HCl, and diluted with 60 mL
|
|
anhydrous Et2O which was the point at which the solution became
|
|
slightly turbid. After a few min, fine white crystals began to form,
|
|
and these were eventually removed, washed with Et2O, and air dried to
|
|
provide 1.28 g 1,4-dimethoxynaphthyl-2-isopropylamine hydrochloride
|
|
(G-N) as the monohydrate salt. The mp was 205-206 !C. Even after 24
|
|
h drying at 100 !C under vacuum, the hydrate salt remained intact.

|
|
EXTENTIONS AND COMMENTARY: The evaluation of this compound is not yet
|
|
complete. An initial trial at the 2 milligram level showed neither
|
|
central action, nor toxicity. It could be guessed from the activity
|
|
of the two-carbon counterpart, that an active level will be found in
|
|
the tens of milligrams area. But, as of the moment, this level is not
|
|
known to anyone, anywhere, because no one has yet defined it. And
|
|
when the potency is finally found out, the nature of the activity will
|
|
also have been found out, all the result of a magical interaction of a
|
|
virgin compound with a virgin psyche. At the immediate moment, the
|
|
nature of G-N is not only unknown, it has not yet even been sculpted.
|
|
There can be no more exciting area of research than this, anywhere in
|
|
the sentient world.

#87 HOT-2; 2,5-DIMETHOXY-4-ETHYLTHIO-N-HYDROXYPHENETHYLAMINE
|
|
|
|
SYNTHESIS: A solution of 5.50 g
|
|
2,5-dimethoxy-4-ethylthio-'-nitrostyrene (see under 2C-T-2 for its
|
|
preparation) was made in 80 mL boiling anhydrous THF. On cooling,
|
|
there was some separation of a fine crystalline phase, which was kept
|
|
dispersed by continuous stirring. Under an inert atmosphere there was
|
|
added 3.5 mL of a 10 M borane dimethylsulfide complex, followed by 0.5
|
|
g sodium borohydride as a solid. There was a slight exothermic
|
|
response, and the color slowly faded. Stirring was continued for a
|
|
week. There was then added 40 mL H2O and 20 mL concentrated HCl, and
|
|
the reaction mixture heated on the steam bath for 15 minutes, with the
|
|
THF at reflux. After cooling again to room temperature, all was
|
|
poured into 1 L H2O and washed with 3x75 mL CH2Cl2, which removed all
|
|
of the color but little of the product. The aqueous phase was made
|
|
basic with 25% NaOH, and extracted with 3x75 mL CH2Cl2. The extracts
|
|
were pooled and the solvent removed under vacuum to give a residue of
|
|
3.88 g of an amber oil. This was dissolved in 30 mL IPA, acidified
|
|
with concentrated HCL to a bright red on universal pH paper, and then
|
|
diluted with 200 mL anhydrous Et2O. After a short period of time,
|
|
crystals started to form. These were removed by filtration, washed
|
|
with Et2O, and air dried to constant weight. Thus was obtained 2.86 g
|
|
2,5-dimethoxy-4-ethylthio-N-hydroxyphenethylamine hydrochloride
|
|
(HOT-2) as off-white crystals, with a melting point of 122 !C with
|
|
decomposition. Anal. (C12H20ClNO3 S) H; C: calcd, 49.05; found,
|
|
50.15, 49.90.
|
|
|
|
DOSAGE: 10 - 18 mg.
|
|
|
|
DURATION: 6 - 10 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 12 mg) Tastes OK. Some activity noticed
|
|
in 30 minutes. Very smooth rise with no body load for next two hours.
|
|
At that time I noted some visuals. Very pleasant. The bright spots
|
|
in the painting over the fireplace seemed to be moving backwards (as
|
|
if the clouds were moving in the painting). Upon concentrating on any
|
|
item, there was perceptual movement with a little flowing aspect. The
|
|
visuals were never all that strong, but could not be turned off during
|
|
the peak. At hour three there was still some shimmering, and it was
|
|
hard to focus when reading. Additionally, there was difficulty
|
|
concentrating (some mental confusion). The material seemed to allow
|
|
erotic actions; there was no problem about obtaining an erection. I
|
|
ate very well, some crazy dips, as well as a fabulous cake. A very
|
|
gentle down trend and I became close to baseline by 6 or 7 PM. I had
|
|
no trouble driving. The dosage was good for me. I did not want more
|
|
or less.
|
|
|
|
(with 12 mg) Comes on smoothly, nicely. In 40 minutes I feel nice
|
|
euphoria, feel home again. Then I begin to get uncomfortable
|
|
feelings. Gets more and more uncomfortable, feel I am sitting on a
|
|
big problem. Blood pressure, pulse, go up considerably. Have hard
|
|
time communicating, lie down for a while, get insight that most
|
|
important thing for me to do is learn to listen, pay attention to what
|
|
is going on. I do this the rest of the day, at first with
|
|
considerable difficulty, then easier and easier. Discomfort stays
|
|
with me for several hours, and although I get more comfortable towards
|
|
the end of the day, I am never animated or euphoric. I feel very
|
|
humbled, that I have a great deal to work out in my life. The next
|
|
day I find myself very strong and empowered. I see that all I have to
|
|
do is let things be as they are! This feels marvelous, and a whole
|
|
new way to be Q much more relaxed, accepting, being in the moment. No
|
|
more axes to grind. I can be free.
|
|
|
|
(with 18 mg) I found myself with complete energy. I was completely
|
|
centered with an absolute minimum of the dark edges that so often
|
|
appear as components of these experiences. The ease of talking was
|
|
remarkable. There was some blood-pressure run-up in the early part of
|
|
the day, but that quickly returned to normal. I would repeat without
|
|
hesitation.
|
|
|
|
EXTENSIONS AND COMMENTARY: Again, a case of where the potency range of
|
|
the Rhot,S or hydroxylated compound (HOT-2, 10 to 18 milligrams) is
|
|
very similar to that of the non-hydroxylated prototype (2C-T-2, 12-25
|
|
milligrams). It seems to be a well tolerated, and generally pleasant
|
|
material, with a mixture of sensory as well as insightful aspects.
|
|
Something for everyone.

#88 HOT-7; 2,5-DIMETHOXY-N-HYDROXY-4-(n)-PROPYLTHIOPHENETHYLAMINE
|
|
|
|
SYNTHESIS: A well-stirred solution of 1.77 g
|
|
2,5-dimethoxy-'-nitro-4-(n-propylthio)styrene (see under 2C-T-7 for
|
|
its preparation) in 20 mL anhydrous THF was placed in an He atmosphere
|
|
and treated with 1.5 mL of 10 M borane-dimethyl sulfide complex. This
|
|
was followed by the addition of 0.2 g sodium borohydride, and the
|
|
stirring was continued at room temperature for a week. The volatiles
|
|
were removed under vacuum, and the residue was treated with 20 mL
|
|
dilute HCl and heated on the steam bath for 30 min. The cooled yellow
|
|
solution set up as solids. The addition of H2O was followed by
|
|
sufficient K2CO3 to make the aqueous phase basic. All efforts to work
|
|
with an acidified aqueous phase resulted in terrible emulsions. The
|
|
basic phase was extracted with 3x75 mL CH2Cl2, and the pooled extracts
|
|
washed with H2O, then stripped of solvent under vacuum. The residual
|
|
yellow oil was dissolved in 20 mL IPA, neutralized with 15 drops of
|
|
concentrated HCl, and then diluted with 50 mL anhydrous Et2O. After a
|
|
few minutes stirring, a white crystalline solid separated. This was
|
|
removed by filtration, washed with Et2O, and air dried to constant
|
|
weight to provide 0.83 g of
|
|
2,5-dimethoxy-N-hydroxy-4-(n)-propylthiophenethylamine hydrochloride
|
|
(HOT-7).
|
|
|
|
DOSAGE: 15 - 25 mg.

DURATION: 6 - 8 h.

QUALITATIVE COMMENTS: (with 15 mg) I am lightheaded, and maybe a
|
|
little tipsy. I am well centered, but I donUt want to go outside and
|
|
meet people. Shades of alcohol woozy. The effects were going already
|
|
by the fifth hour and were gone by the seventh hour. I would call it
|
|
smoothly stoning.
|
|
|
|
(with 22 mg) The transition into the effects was a bit difficult,
|
|
with a faint awareness in the tummy. But by the second hour it was
|
|
quite psychedelic, and the body was not thought of again, except in
|
|
terms of sexual fooling around. Very rich in eyes-closed imagery, and
|
|
very good for interpretive and conceptual thinking. But the eyes-open
|
|
visuals were not as much as they might have been. At the seventh
|
|
hour, drifted into an easy sleep.
|
|
|
|
(with 22 mg) The experience was very positive, but at each turn there
|
|
seemed to be a bit of sadness. Was it a complete plus three
|
|
experience? Not quite. But it didnUt miss by much. The erotic
|
|
explorations somehow just failed to knit by the thinnest of margins.
|
|
It was a truly almost-magnificent experience.
|
|
|
|
EXTENSIONS AND COMMENTARY: There is a working hypothesis that has been
|
|
growing in substance over the last few years in this strange and
|
|
marvelous area of psychedelic drugs. It all was an outgrowth of the
|
|
rather remarkable coincidence that I had mentioned in the discussion
|
|
that followed MDOH. There, an assay of what was thought to be MDOH
|
|
gave a measure of activity that was substantially identical to MDA,
|
|
and it was later found out that the material had decomposed to form
|
|
MDA. So, MDA was in essence rediscovered. But when the true, valid,
|
|
and undecomposed sample of MDOH was actually in hand, and assayed in
|
|
its own rights, it was found to have a potency that really was the
|
|
same as MDA. So, the working hypothesis goes something like this:
|
|
|
|
AN N-HYDROXY AMINE HAS APPROXIMATELY THE SAME POTENCY AND THE SAME
|
|
ACTION AS ITS N-HYDROGEN COUNTERPART.
|
|
|
|
Maybe the N-hydroxy compound reduces to the N-H material in the body,
|
|
and the latter is the intrinsically active agent. Maybe the N-H
|
|
material oxidizes to the N-hydroxy material in the body, and the
|
|
latter is the intrinsically active agent. Either direction is
|
|
reasonable, and there is precedent for each. The equivalence of MDA
|
|
and MDOH was the first suggestion of this. And I have made a number
|
|
of NH vs. NOH challenges of this hypothesis. The interesting 2C-T-X
|
|
series has provided a number of amines that are amenable to
|
|
N-hydroxylation, and this is the first of them. And, after all, if
|
|
you put a hydroxy (HO) group on a thio material (T), you have a HOT
|
|
compound.
|
|
|
|
So, as far as nomenclature is concerned, the family of N-hydroxy
|
|
analogues of N-H amines is known as the HOT family.
|
|
|
|
How does HOT-7 compare with 2C-T-7? They are almost identical. The
|
|
same range of dose (centering on 20 milligrams) and if anything,
|
|
perhaps slightly less long lived. Lets try some other N-hydroxys!

|
|
|
#89 HOT-17; 2,5-DIMETHOXY-4-(s)-BUTYLTHIO-N-HYDROXYPHENETHYLAMINE
|
|
|
|
SYNTHESIS: To a well-stirred solution of 6.08 g
|
|
2,5-dimethoxy-4-(s)-butylthio-'-nitrostyrene (see under 2C-T-17 for
|
|
its preparation) in 80 mL anhydrous THF under a He atmosphere, there
|
|
was added 3.5 mL 10 M borane dimethylsulfide complex, followed by 0.5
|
|
g of sodium borohydride. As the stirring continued, the slightly
|
|
exothermic reaction slowly faded from bright yellow to pale yellow,
|
|
and eventually (after three days stirring) it was substantially
|
|
colorless. There was then added 80 mL of 3 N HCl and the mixture
|
|
heated on the steam bath for 1 h, and then allowed to return to room
|
|
temperature. An additional 600 mL H2O was added (there was a
|
|
combination of crystals and globby chunks in the aqueous phase) and
|
|
this was then extracted with 3x75 mL CH2Cl2. The color went
|
|
completely into the organic phase. This was washed with 2x50 mL
|
|
aqueous K2CO3, yielding a rusty-red colored CH2Cl2 solution, which on
|
|
removal of the solvent, yielded 4.5 g of a red oil. A side effort to
|
|
make the sulfate salt at this stage with H2O and a little H2SO4,
|
|
indeed gave solids, but all of the color remained in the sulfate salt.
|
|
The red oil was dissolved in 45 mL IPA and neutralized with
|
|
concentrated HCl to bright red, not yellow, on universal pH paper.
|
|
The addition of 350 mL anhydrous Et2O instituted the slow
|
|
precipitation of white crystals. After filtering and air drying,
|
|
there was obtained 1.32 g
|
|
2,5-dimethoxy-4-(s)-butylthio-N-hydroxyphenethylamine hydrochloride
|
|
(HOT-17). The aqueous phase from above was just neutralized with 25%
|
|
NaOH (cloudy, slightly pink color) and then made basic with K2CO3 (the
|
|
color becomes green). This was extracted with 3x75 mL CH2Cl2, the
|
|
extracts pooled, and the solvent removed to yield 0.5 g of a white
|
|
oil. This was dissolved in 5 mL IPA, neutralized with concentrated
|
|
HCl, and diluted with a equal volume of Et2O. An additional 0.36 g of
|
|
product was thus obtained.
|
|
|
|
DOSAGE: 70 - 120 mg.
|
|
|
|
DURATION : 12 - 18 h.
|
|
|
|
QUALITATIVE COMMENTS: (with 70 mg) There was a light feeling, a
|
|
little off-the-ground feeling, which made walking about a most
|
|
pleasant experience. No distortion of the senses. And there was no
|
|
sense of the beginning of a drop of any kind until about the eighth
|
|
hour. Sleeping was a bit tricky but it worked out OK (at the twelfth
|
|
hour of the experience). A completely valid ++.
|
|
|
|
(with 120 mg) HOT-17 has an unbelievably GRIM taste Q not bitter, but
|
|
simply evil. There is a steady and inexorable climb for three hours
|
|
to a sound and rolling plus three. There was absolutely no body
|
|
difficulty, but there was still something going on upstairs well into
|
|
the next day. Writing was surprisingly easy; I was completely content
|
|
with the day, and would be interested in exploring it under a variety
|
|
of circumstances.
|
|
|
|
(with 120 mg) This is my first time with this material. It is 4:45
|
|
PM. Small nudge at 30 minutes, but not too real. At one hour,
|
|
threshold, quite real. 6:15 to a +1. By 7:25, +3 about. 7:45, no
|
|
doubt +3. Possibly still climbing; I hope so. No body discomfort at
|
|
all, no apparent body push. This aspect of it is similar to the easy
|
|
body of the HOT-2. However, it's at times like these that I reflect
|
|
on just exactly how hard-headed we two are. I mean, +3 is no longer
|
|
the out-of-body, nearly loss of center state it used to be, four years
|
|
ago. The question intrudes: would a novice experience this as a very
|
|
scary, ego-disintegrating kind of experiment, or not? Silly question
|
|
which answers itself. Yes, of course. At 3 hours, aware of some mild
|
|
time-distortion. More a tendency to not think in terms of clock-time,
|
|
than actual distortion. The mind lazy when attempting to keep track
|
|
of clock time. Feel it would be quite easy and pleasant to continue
|
|
writing. The energy could very well go in that direction. However,
|
|
the idea of the erotic is also quite agreeable. This is, so far, a
|
|
good-humored Buddha area of the self.
|

|
EXTENSIONS AND COMMENTARY: Two virtues sought by some users of
|
|
psychedelic drugs are high intensity and brief action. They want a
|
|
quicky. Something that is really effective for a short period of
|
|
time, then lets you quickly return to baseline, and presumably back to
|
|
the real world out there.
|
|
|
|
Intensity is often (but not always) regulated by dose. The
|
|
pharmacological property of dose-dependency applies to many of these
|
|
drugs, in that the more you take, the more you get. If you want more
|
|
intensity, take a second pill. And often, you get a longer duration
|
|
as an added property. But it is instructive to inquire into the
|
|
rationale that promotes brevity as a virtue. I believe that it says
|
|
something concerning the reasons for using a psychedelic drug. A
|
|
trade off between learning and entertainment. Or between the
|
|
achieving of something and the appearance of achieving something. Or,
|
|
in the concepts of the classics, between substance and image.
|
|
|
|
In a word, many people truly believe that they cannot afford the time
|
|
or energy required for a deep search into themselves. One has to make
|
|
a living, one has to maintain a social life, one has a multitude of
|
|
obligations that truly consume the oh-so-few hours in the day. I
|
|
simply cannot afford to take a day off just to indulge myself in
|
|
such-and-such (choose one: digging to the bottom of a complex concept,
|
|
giving my energies to those whom I can help, to search out my inner
|
|
strengths and weaknesses) so instead I shall simply do such-and-such
|
|
(choose one: read the book review, go to church on Sunday morning, use
|
|
a short-acting psychedelic). The world is too much with us. This may
|
|
be a bit harsh, but there is some merit to it.
|
|
|
|
HOT-17 is by no means a particularly potent compound. The hundred
|
|
milligram area actually has been the kiss of death to several
|
|
materials, as it is often at these levels that some physical concerns
|
|
become evident. And it certainly is not a short lived compound. But,
|
|
as has been so often the case, the long lived materials have proven to
|
|
be the most memorable, in that once the entertainment aspect of the
|
|
experience is past you, there is time for dipping deeply into the rich
|
|
areas of the thought process, and the working through of ideas and
|
|
concepts that are easily available. And when this access is coupled
|
|
to the capability of talking and writing, then a rewarding experience
|
|
is often the result.
|
|
|
|
As with the parent compound, 2C-T-17 itself, the presence of an
|
|
asym-metric carbon atom out there on the (s)-butyl side chain will
|
|
allow the separation of HOT-17 into two components which will be
|
|
different and distinct in their actions. The activity of the racemic
|
|
mixture often is an amalgamation of both sets of properties, and the
|
|
separate assay of each component can often result in a fascinating and
|
|
unexpected fractionation of these properties.
