Trans 4-Methylaminorex via Potassium Cyanate

Chemicals:
28.2 g (0.15 moles) (+/-) norephedrine-HCl. NOTE: (+/-) norephedrine-HCl and (+/-) norspeudoephedrine all fall under the rubric of PPA. You want norephedrine, not norspeudoephedrine.
12.0 g potassium cyanate (KOCN)
172 ml 2M hydrochloric acid (HCl)
20% sodium carbonate (Na2CO3)
Dichloromethane (DCM)
Distilled water (dH2O)

Equipment:
500 ml flat bottom flask
Magnetic hotplate with stir bar
Thermometer

Put 28.2 g PPA-HCl in about 150 ml dH2O in your 500 ml Erlenmeyer. It should all dissolve easily. Next add 12.0 g KOCN and magnetically stir. About 75% of the KOCN should dissolve readily. Reflux the mixture directly on your hotplate. Hotplate should just be hot enough to boil your mixture. At about 35 deg C, all the KOCN should dissolve. Reflux for about 2.5 hours, then allow to cool to room temp. First you should notice a clear oil precipitating to the top. Further cooling will precipitate white flakes on the bottom. Place the flask in your freezer for about ½ hour or until temp drops to 5 deg C. Pour the solution into a pyrex dish and slowly evaporate over low heat. Do not evaporate completely. Next, place the solution back in your washed Erlenmeyer and add about 275 ml dH2O. It should dissolve slightly. Magnetically stir and begin heating the solution. Add 172 ml of 2M HCl and continue stirring and heating until just boiling. At about 50-60 deg C the white solution should turn clear again. Reflux again for about 2.5 hours magnetically stirring the whole time. Allow to cool to room temp. White powder will appear.

Wash the solution 3 times with a small amount of DCM. Isolate the water phase and basify it with your 20% Na2CO3 until no more white powder precipitates. Gravity filter the white powder and allow to dry at room temp with a fan or in an oven at low temp. Your yield should be about 15.5 g (+/-) trans 4-MAR freebase. [Forms Hcl salt readily.]

PPA is controlled the same way PSE is, covered by the combat methamphetamine epidemic act of 2005. At least in the US it is. To top that off the FDA stopped allowing OTC products due to people having strokes. It's still really easy to make though.

done this synthesis (thx jon ) using phenethanolamine as precursor to yield aminorex, done it with norephedrine too afterwards.

the difference was only the appearance of the crystalline freebase, while 4mar can form huge "globs", aminorex tends to form small needle bushes

i would suggest to do it as one-pot synthesis.
recrystallization using TCM or DCM yields pretty freebase crystals, the same with 4mar

Could you please tell something about the effects?

I couldn´t find much information about aminorex.

Does nobody search the original authors notes over at totse ? He explained ( as is available on the dea 's website ) the process by which it was made legal ( illegal ) and the fact that he still got a felony conviction of 5 years ( maybe)  over the synthesis and related lab.

i made a shocking experience with aminorex.

I had some hundred milligrams and started with a 10mg line. I got a bit more alert and my finger got cold. It felt good and i waited an hour or two and did again 5-15mg in 3 little lines. I felt some euphoria and got a compulsion to move. So I walked a bit through the city and i started to sweat very heavily and my whole body got icecold like my fingers.My breath was very heavily and I felt some pressure on my breast.
So i went home and thought that it was maybe to much. I waited till the late evening and got very sleepy and tired. My breath was still very heavily and I thought i should sleep. So I tried to sleep and felt in some kind of a half sleep half awake state. I sweated the whole night very much and i woke from time to time up with the feeling that i can't breathe. Also i dreamt very confusing horrifying shit.
In my opinion it was the craziest night i ever had and i thought that i will die every minute. my breast was quaking like it would explode and I still got not much air in my lungs. At the next morning my breath was still very bad and fast. But not as fast as in the night so I knew that I should wait and it will go away.

At nearly 3pm the next day it was gone and i thought that aminorex is some pretty bad shit. I read that aminorex and 4-Methylaminorex can cause a pulmonary hypertension and in my opinion I had it that night. Also i read that both can cause easily seizures. But the half-life of aminorex is not as long as the half-life of 4-Methylaminorex so I don't want to know how it would if you have this symptoms on 4-Methylaminorex.

After this I didn't took it a second time. It was in my opinion too risky and the night was like hell for me.

So if somebee here wants to try some methylaminorex or aminorex I can only say that he or she should take care and be careful.

yeah i must have been totally stupid to attempt a synthesis based on only the information that it is 4x anorectic stronger than is 4mar

toady, quite a few is an understatement, IIRC it were a few hundred only in switzerland and germany

yeah well quite the same as someone would expect an equal fun level of fentanyl than morphine gives, based on its analgesic potency

yeah but thats not the effect of aminorex only of 4-methylaminorex.
i still wonder about activity of the zinc reduced imine made in the same reaction with l-ephedrine, or about the 4mar one n-methylated on outer nitrogen, as antoncho stated "2N-"4methylaminorex? anyone got experiences?

Fuck yeah!  A good otc route to phenmetrazine would be the shiznit!

no just heat it directly on hotplate rolling boil add water to acount for evaporation.
