Herkese merhaba. Bu tarifi kullanarak küçük ölçekte bir miktar amfetamin yapmaya çalıştım, ancak başarısız oldum. Her şey yolunda görünüyordu, kuruduktan sonra ürünüm bir miktar kırmızılık içeren beyaz bir toz gibi görünüyordu. Eğer amfetamin sülfat olsaydı (ki yapmaya çalışıyordum), verim %84 olurdu. Sorun şu ki, bu amfetamin değil.

Fizyolojik etkiler
20-30 mg denedim, kesinlikle stimülasyon vardı, ama aynı zamanda ateşe ve görünüşe göre bağışıklıkta bir düşüşe neden oldu: birkaç gün üst üste aldığım her iki seferde de solunum yolu enfeksiyonlarına yakalandım (ilk seferinde bunun bir tesadüf olduğunu düşündüm). Bunu alan başka bir kişi 90 mg'a kadar herhangi bir uyarılma yaşamadı, sadece biraz ağız kuruluğu yaşadı. İkimizin de uyarıcılara karşı toleransı yok.

Kimyasal testler
1 g toz 10 ml H2O içinde tamamen çözünüyor.
Bir test tüpünde ölçülen toz kütlesine fazla miktarda NaOH çözeltisi eklediğimde, yaklaşık olarak doğru hacimde amonyak kokan bir serbest baz elde ettim. Freebaz tabakasını ayırdım, CaCl2 ile kuruttum ve asit ile titre etmeye çalıştım. Sonuç olarak, serbest bazın molar kütlesini yaklaşık 171 olarak ölçtüm (ve amfetamin için 135'tir). Ölçümlerim çok hassas olmasa da, aradaki fark yalnızca ölçüm hatalarıyla açıklanamayacak kadar büyük.

Prosedürden sapmalarım

1) P2NP eklerken, bunun saatler alacağını fark ettim, bu yüzden sabırsızlandım ve reaksiyon şişesini oda sıcaklığında bir su banyosuna daldırdım. Bundan sonra P2NP'yi neredeyse tek seferde ekleyebildim ve karışımın sıcaklığı 40-50 °С'yi geçmedi.
2) Videoyu takip ediyordum, bu yüzden IPA'yı buharlaştırmadım ve doğrudan IPA / freebase katmanına conc. sülfürik asit ekledim.
3) O anda hiç asetonum yoktu, bu yüzden asitleştirmeden önce eklemedim ve filtrelenmiş "amfetamin sülfat" macununu IPA ile yıkadım.
4) IPA asetondan daha az uçucudur, bu yüzden çökeltimi sabit ağırlığa kadar kurutmak için birkaç saat fırına koymak zorunda kaldım. Fırındaki sıcaklık 80 °С'yi geçmedi.

Asıl soru şu: Nerede yanlış yaptık? Düşük verim veya hiç ürün olmaması beni şaşırtmazdı, ama amfetamin olmayan bir aminden iyi bir verim almak?!

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.
