Methamphetamine via Leuckart reaction

[Researcherr]

Forum members greetings

Because there is not enough information about ratios on such molar scale I need your help!
Let me ask you is here someone who has experience with Leuckart reaction to produce Methamphetamine?
Can someone who has experience on such scale please write ratios for NMF-P2P-FORMIC ACID, how to start the reaction, slowly and gradually heat it up or just ramp the temperature to 180 and cook for 24 - 48 hours?
What ratios of HCL or NaOH then use in the hydrolisis?
What are the obtained yields if doing let's say 1L P2P reaction via this method?

Sorry I forgot to write the scale of reaction is 1L P2P
So I would need ratios for this scale if anyone is willing to help

Complete amphetamine freebase (A-oil) synthesis from P2P(10L scale)

I added the 2 ways of N-Formylamphetamine Hydrolysis and as always is MY way and it works for ME don't means is the only and official way. N-Formylamphetamine 1. Put 10L of P2P in the reactor, add 15L of formamide and 7L of formic acid, slow stirring with reflux during 5 hours at 140/150C. 2...

Here you go, maybe take an idea from here, can't imagine why you wouldn't be able to scale the same way, but maybe I'm wrong

Thank you, I know this process very good, but Leuckart for Amphetamine and Leuckart for Methamphetamine is different in chemicals and ratios so I still look for someone with experience to help out with correct ratios, times and such things
