A oil

[Cryptos82]

Does anyone have an easy method to go from A oil straight to meth or is this even possible, excuse my lack of knowledge

Yes, there are some methods, although not sure about "easy" for average user.
One of it looks like this:
1) Reflux your "A-oil" in double volume of ethyl formate (i.e 1:2 w/v) for at least 24h, then concentrate in to dryness under vacuum.
2) Reduce your N-formyl intermediate with LAH in THF under inert atmosphere (may take some days to go to completion).

Thanks my friend, I produce top quality A oil but have just received order for meth, never done before but if I can get from BMK powder to A oil can’t be that much harder

 

[FENTAMAS]

Preferably to go directly from BMK to Meth, than through amphetamine, as the last method isn't suitable for the large-scale synthesis.

Ye I have been shown this way I cook with foramide and Formic 2nd cook do I swap out the formamide with methyl formamide or something can’t remember exact name my friend

 

[Tovenaar]

Yes that is leuckart, instead of formamide use n-methyl formamide.

If you want to go from amp to meth, i would use formaldehyde 40% in alcohol with formic acid, and reflux…
