Hello, which active ingredients have a similar effect to pregablin? What can you replace pregablin with?

for 1 liter n-formyl mix1,2-1,5 liter methanol, 700-850 gr KOH and 0,3-0,6 liter water. dissolve KOH complete. After it has cooled down a bit, put it in the fridge for a few hours. put this mix under stirring to the n-formyl and let mix half hour without heat. after go to 85-90C. 85-90 bacause...

i read sodium chloride first time for this synthesis. i have read this synthesis from several sources and you are the only one using it. what is the benefit?

N-Formylamphetamine Hydrolysis by NaOH way 1. Put the 11L of N-Formylamphetamine in the reactor, add 13L previous cold 65% NaOH solution slow stirring with reflux during 2-3 hours at 110C. 2. Stop heating and cool it at RT use here methanol + less water and NaOH or KOH (for me KOH better), with...

i found this shortly. Interesting topic, does anyone know more about this? “ reprocess the L- into D- by oxidizing it and reaminating it as described in the “critique” of the Phrack synthesis.”

shortly: benzylcyanid-apaan-p2p- +formamid+formic acid- n-formylamphetamin- reflux koh+methanol+water-steam distillation- freebase-amphetaminsulfate

of course i write soon detailed route

hello, I need help please. I need methylamine hydrochloride, but have only methylamin 40% in water solution. how can I remove water easily and safe? thanks

i have actually Methylamin-Water solution. How to remove water? Water is dangerous in this reaction i think

I have successfully synthesized amphetamine sulfate from benzyl cyanide. When I first discovered this forum I was a total amateur. After much reading and generous help from @G.Patton I have successfully completed. Thanks very much

i have pure sodium, not sodium amid. how should i work? please @G.Patton

@OrgUnikum great :) thank you very much

I would strongly suggest to do this in one step, methanol or ethanol as solvent and to use the formic acid salt of a-methylbenzylamine in the amination step for better yields the acid serving also as hydrogen donor in the Imine reduction. Although the ph in the debenzylation should be acidic I...

hello, "1. Put the 11L of N-Formylamphetamine in the reactor, add 13L previous cold 65% NaOH solution slow stirring with reflux during 2-3 hours at 110C." I read here somewhere that hydrolysis with NaOH + methanol gives a much higher yield. can you confirm that? if so, can you please describe...

and chloroethyl chloroformate can also be used this instead of Pd/C ?

that means for 1000gr P2P max. 100gr Pd/C ? and how often can i use Pd/C?

how much should be used instead 475gr? @mygodson

don’t understand. doesn’t work with raney nickel?

can you please explain for beginner? don’t work with raney nickel? reduced 5% to 10% ?
