Hallo zusammen. Ich habe versucht, mit diesem Rezept in kleinem Maßstab Amphetamin herzustellen, bin aber gescheitert. Alles schien in Ordnung, nach dem Trocknen sah mein Produkt wie weißes Pulver mit einem Hauch von Rötung aus. Wenn es sich um Amphetaminsulfat handeln würde (das ich herzustellen versuchte), wäre die Ausbeute 84 %. Das Problem ist, dass es sich nicht um Amphetamin handelt.

Physiologische Wirkungen
Ich habe 20-30 mg ausprobiert, es gab definitiv eine Stimulierung, aber es verursachte auch Fieber und anscheinend einen Rückgang der Immunität: beide Male, als ich es mehrere Tage hintereinander nahm, erkrankte ich an Atemwegsinfektionen (beim ersten Mal dachte ich, es sei ein Zufall). Eine andere Person, die es eingenommen hat, verspürte bei einer Dosierung von bis zu 90 mg keine Stimulation, sondern nur eine gewisse Mundtrockenheit. Keiner von uns beiden hat eine Toleranz gegenüber Stimulanzien.

Chemische Tests
1 g des Pulvers löst sich vollständig in 10 ml H2O auf.
Als ich überschüssige NaOH-Lösung zu einer abgemessenen Menge des Pulvers in einem Reagenzglas hinzufügte, erhielt ich ein ungefähres Volumen an freier Base, die nach Ammoniak roch. Ich trennte die Freebase-Schicht ab, trocknete sie mit CaCl2 und versuchte, sie mit Säure zu titrieren. Das Ergebnis war, dass die molare Masse der Freebase etwa 171 betrug (und die des Amphetamins 135). Meine Messungen waren zwar nicht sehr genau, aber der Unterschied ist dennoch zu groß, um allein durch Messfehler erklärt werden zu können.

Meine Abweichungen vom Verfahren

1) Bei der Zugabe von P2NP wurde mir klar, dass es Stunden dauern würde, also wurde ich ungeduldig und tauchte den Reaktionskolben in ein Wasserbad mit Raumtemperatur. Danach konnte ich P2NP fast auf einmal zugeben, und die Temperatur der Mischung überstieg nicht 40-50 °С.
2) Da ich mich an das Video gehalten habe, habe ich das IPA nicht verdampft und die IPA/Freebase-Schicht direkt mit Schwefelsäure versetzt.
3) Da ich gerade kein Aceton zur Hand hatte, habe ich es vor dem Ansäuern nicht hinzugefügt und die gefilterte "Amphetaminsulfat"-Paste mit IPA gewaschen.
4) Da IPA weniger flüchtig ist als Aceton, musste ich den Niederschlag mehrere Stunden in einen Ofen stellen, um ihn auf ein konstantes Gewicht zu trocknen. Die Temperatur im Ofen hat 80 °С nicht überschritten.

Die große Frage ist also, wo ist es schief gegangen? Eine geringe Ausbeute oder gar kein Produkt würde mich nicht überraschen, aber eine gute Ausbeute an einem Amin, das kein Amphetamin ist?!

The method as described here lacks all product workup/cleanup and and as such provides a very dirty and unclean Amphetamine, in special as NasBH4 reductions are all not giving very clean product. Purple MDMA and such.
I know the physiological effects like fever like very well and it is just the missing cleaning trust me.
There are several ways to do the workup, from distillation, normal, vacuum or steam of the base or dissolving the sulfate in water and washing this several times with toluene or petrolether or my favorite: 50/50 mix of petrol ether and Ethylacetate. Then evaporate the water and wash the resulting salt with copious amounts of Acetone and petrol ether as last. Already the simple washings give you a consumable product which does not make you sick like the crap which contains borate salts or else.

Even with the dirtiest amp he would have felt it just fine....guaranteed he got "almost amp" mainly riddled with hydroxylamine. This reaction goes south on people all the time. They have wayyyy too much nabh4 left when it's time to add the copper and with the heat the nanoparticles aggregate and become completely useless as a catalyst....fully useless... and leave semi reduced product. The only way I've been able to get around that is by reducing 1st in methanol/thf to propane then extracting and then using anyone of the zinc/formic acid combos.... for the nitro. Zero Michael addition.

I tried it today, but something must have gone wrong..I followed the instructions exactly, but in the end there is more than there should be. What could have happened? Can anyone give me advice? Can it be cleaned? Thank you for every answer

Please. How do I have a reaction more nabh4? I threw in for 6 hours but still not much nabh4 dissolved. In the end, when I added acid, the whole thing thickened after filtration, a white substance remained, but I suppose it's nabh4.. I followed the instructions I don't know what's wrong.

My mescaline guide might help for 1 or 2 mol amounts. Possibly up to 500 g+ in a 20 L reaction vessel.

The same procedure for P2NP as with Mescaline nitrostyrene, however I do not know if it is more reactive. Have not worked with it.

Take a look here:

Or posted here (if starting from benzaldehyde):

My friend and I always cooked amphetamine in the forest.
That is, for synthesis we really only needed 3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons that show the reaction.

My role was always bring and serve, but we produced this product of 99.8% purity.
We had no competition in Moscow :/

we didn't use fucking acetone because it's bad for your health

At one point in Russia, they suddenly cut off the liquid propen supply—left a bunch of wannabe cooks totally clueless. Product turned out nasty as hell, colors ranging from sketchy pinks to filthy yellows and straight-up horrifying oranges. But my homie was different—he was one of the few who knew the synthesis inside and out. Back in the day, he cooked pristine pervitin for the whole block, but dude got busted—hit him with a solid 20-year stretch. Luckily there’s a war poppin' off, so he'll probably get tossed onto the front lines and bounce back home early. Then we'll pick right back up where we left off.

but you say "...3 construction basins, Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." and in your list of reagents only hydrochloric acid

I can hit him up and get the full cook recipe—it's fuckin' one-of-a-kind.

in this synthesis using only this reagents "...Phenyl-nitropropene, several boxes of mercury thermometers, hydrochloric acid, gasoline and some special ribbons..." amp sulfate cannot be obtained.

with hydrochloric acid obtain amp hydrochloride
with sulphuric acid obtain amp sulphate

Your reagents list remind different synthesis way (Al/Hg approach). Why did you write this post under NaBH4 method? It's, also, interesting about HCl and sulphate salt.
