3,5-DIMETHOXY-4-ETHOXYAMPHETAMINE
SYNTHESIS: A
solution of 3.6 g
syringaldehyde (
3,5-dimethoxy-4-
hydroxybenzaldehyde) in 50 mL MeOH was combined with a
solution of 3.7
g 85% KOH in 75 mL warm MeOH. This clear
solution suddenly set up to
crystals of the
potassium salt, too thick to stir satisfactorily. To
this suspension there was added 7.4 g
ethyl iodide (a large excess)
and the mixture was held at reflux tem
perature with a heating mantle.
The solids eventually loosened and re
dissolved, giving a clear
amber-colored smooth-boiling
solution.
Refluxing was maintained for 2
days, then all
volatiles were removed under vacuum. The residue was
dissolved in 400 mL H2O, made strongly basic with 25%
NaOH, and
extracted with 4x100 mL
CH2Cl2. The pooled extracts were washed with
saturated brine, and the
solvent removed under vacuum to give 3.3 g of
a pale amber oil which set up as
crystals of
3,5-dimethoxy-4-ethoxybenzaldehyde with a mp of 47-48 °C. A small
sample re
crystallized from
methanol had a mp of 48-49 °C.
A
solution of 3.3 g
3,5-dimethoxy-4-ethoxybenzaldehyde in 25 mL
nitroethane was treated with 0.5 g
anhydrous ammonium acetate and
heated on the steam bath for 36 h. The
solvent/reagent was removed
under vacuum giving a thick yellow-orange oil that was
dissolved in
two volumes hot MeOH. As this cooled,
crystals appeared
spontaneously, and after cooling in ice for a short time, these were
removed by filtration and washed sparingly with cold MeOH, Air drying
to constant weight provided 2.2 g
1-(3,5-dimethoxy-4-ethoxyphenyl)-2-nitropropene with a mp of 84-85 °C.
The mother liquors, on standing overnight,
deposited large chunks of
crystalline material which was isolated by
decantation, ground up
under a small amount of
methanol, then re
crystallized from 60%
EtOH.
A second crop of 0.7 g of the
nitrostyrene was thus obtained, as
canary-yellow
crystals with a mp of 83-85 °C.
A
solution of 2.7 g
1-(3,5-dimethoxy-4-ethoxyphenyl)-2-nitropropene in
20 mL
anhydrous THF was added to a suspension of 2.0 g LAH in 150 mL
warm THF. The mixture was held at reflux for 48 h. After stirring at
room tem
perature for another 48 h, the excess
hydride was destroyed by
the addition of 2.0 mL H2O in 10 mL THF, followed by 2.0 mL 15%
NaOH
and then an additional 6.0 mL H2O. The inorganic salts were removed
by filtration, and the filter cake washed with THF. The combined
mother liquor and washings were stripped of
solvent under vacuum
leaving a yellow oil with some inorganic salts still in it. This was
dissolved in 300 mL
CH2Cl2, washed with dilute
NaOH, and extracted
with 3x150 mL 1 N HCl. The pooled extracts were washed once with
CH2Cl2 made basic with 25%
NaOH, and extracted with 3x100 mL CH2Cl2.
The combined organics were washed with saturated brine, and the
solvent removed under vacuum to yield about 2 mL of a colorless oil.
This was
dissolved in 10 mL IPA, neutralized with concentrated HCl (10
drops were required), and diluted with 125 mL
anhydrous Et2O. The
slight cloudiness gradually became the formation of fine white
crystals. After standing at room tem
perature for 2 h, these were
removed,
Et2O washed, and air dried. There was thus obtained 1.9 g of
3,5-dimethoxy-4-ethoxyamphetamine hydrochloride (3C-E) as brilliant
white
crystals.
DOSAGE: 30 - 60 mg.
DURATION: 8 - 12 h.
QUALITATIVE COMMENTS: (with 40 mg) It developed into a strange and
indefinable something. It is unworldly. I am very much in control,
but with an undertone of unreality that is a little
reminiscent of
high doses of LSD. If there were a great deal of sensory input, I
might not see it. And if I were in complete sensory quiet I would
miss it, too. But just where I am, I can see it. Eerie state of
awareness. And by the 8th hour I am sober, with no residue except for
some slight teeth clenching, and pretty much disbelieving the whole
thing.
(with 60 mg) Visuals very strong, insistent. Body discomfort
remained very heavy for first hour. Sense of implacable imposition of
something toxic for a while. I felt at the mercy of uncomfortable
physical effects--faint or pre-nausea, heavy feeling of tremor
(although tremor actually relatively light) and general dis-ease,
un-ease, non-ease. Kept lying down so as to be as comfortable as
possible. Fantasy began to be quite strong. At first, no eyes closed
images, and certainly anti-erotic. 2nd hour on, bright colors,
distinct shapes--jewel-like--with eyes closed. Suddenly it became
clearly not anti-erotic. That was the end of my bad place, and I shot
immediately up to a +++.
Complex fantasy which takes over--hard to
know what is real, what is fantasy. Continual erotic. Image of
glass-walled apartment building in mid-desert. Exquisite sensitivity.
Down by ? midnight. Next morning, faint flickering lights on looking
out windows.
EXTENSIONS AND COMMENTARY: This is an interesting closing of the
circle. Although mescaline launched the entire show, the first half
could be called the
amphetamine period, with variations made on all
aspects of the molecule except for that three-
carbon chain. And it
was found that the 4-
substitution position was of paramount importance
in both the potency and the quality of action of a compound. Then,
looking at the long-ignored chain, lengthening it by the addition of a
carbon atom eliminated all
psychedelic effects and gave materials with
reduced action. The action present was that of an anti
depressant.
But removing a
carbon atom? This returned the search to the world of
mescaline, but with the knowledge of the strong influence of the
4-position
substituent. The two-
carbon side-chain world was
rediscovered, principally with
2C-B and
2C-D, and the
4-ethoxy-
analogue of mescaline, E. This second half of the show could
be called the
phenethylamine period. And with compounds such as 3C-E
which is, quite simply, Escaline (or E) reextended again to a 3-
carbon
chain
amphetamine, there is a kind of satisfying closure. A
fascinating compound, but for most subjects a little too heavy on the
body.
