    Mescaline by the catalytic hydrogenation of 3,4,5-trimethoxynitrostyrene
-------------------------------------------------------------------------------

By KrZ:

Place the following in a 2L RBF;

250g 3,4,5-Trimethoxybenzaldehyde
500ml Nitromethane
10g Ammonium Acetate (anhydrous)

•Gently reflux for 5-6 hours
•Cool and distill off any residual nitromethane.
-If the crystaline mass prevents distillation, remove it by vacuum filtration
 and use what is collected OR distill off the filtered nitromethane solution to
 collect an additional crop of crystals (If the crystals are stuck in the flask
 skip to the next step)
•Add enough boiling MeOH to dissolve the entire mass (If it's stuck in the
flask, if not skip this step, filter, and recrystalize once from boiling MeOH)
•Decant, cool and vacuum filter, repeat the recrystalization if the crystals are
not a pure yellow color (which they usually are)

Hydrogenation;

15g Pd/C 5%
175g 3,4,5TMBnitrostyrene
2.5L Anhydrous EtOH
100ml 31.45% HCl

•Add reagents to the keg, begin vigorous stirring
•Remove atmosphere and pressurize to 75psi with H2
•React for 8-10 hours or until H2 uptake has completely ceased
•Evacuate H2 outside, vacuum out interior of vessel, allow H2 to clear, THEN
 open the vessel
•Vacuum filter off Pd/C
•Re-filter through celite for maximum Pd/C recovery/removal
•Distill the mixture down until the Ethanol fraction begins to cease
•Cool and take up what is left in 2L 3N HCl
-Your remainder may look somewhat black/brown here, but don't worry, this will
 all be cleared up. If the hydrogenation did not go to completion some unreacted
 nitrostyrene will remain, this should be filtered from the solution.
•Wash with 2x125ml DCM
•Basify to pH>11 dropwise and with stirring with saturated NaOH solution
•Extract 3x125ml DCM
•Dry over NaSO4 (250g) for 15 minutes
•Filter off NaSO4 and bubble DCM with HCl(g) anhydrous. After crystalization
 ceases it can be advantageous to filter and redry the DCM with another 100g
 NaSO4, then bubble some more.
•Collect HCl salt crystals by filtration

Final mass yield = 168.74g M•HCl

"Prisoner 655321. Into a Ghetto Reactor (tm) there was placed 890g 3,4,5-MeO-
nitrostyrene (you know which one), this was dissolved in EtOH (2l), and 80ml of
from the bottle concrete cleaner was added (31.45%), then 25g of 3% Pt/C was
added and the reactor was stirred vigorously. The reaction was cooled in an ice
bath. Atmosphere was removed and 80psi of H2 was added. Pressure was supplied as
needed and when the reaction was complete (6hrs), it was filtered through
celite, washed with DCM, and then basified with aq. ammonia (500ml), it was then
extracted with 4 200ml portions of DCM. The DCM was bubbled with HCl gas to
produce, 588.54g of Mescaline.
