NaBH4 route gives exellent yields.Only problem is that NaBH4 is expensive and might not be available for certain bees.Yields w/w go over 100%.
Then there's that platinum dioxide(Adams catalyst) method @ 3 atm H pressure with yields w/w in 90's.
Both methods are pretty cold.NaBH4 rxn contents must be kept under 10C,but i can't remember the temp needed in PtO2 method
The labs in holland use PtO2. I read in the a magazine overthere. Some chemists produced in order of some maffia people, in a week 300 kilo's of MDMA freebase. The gazzing and stuff was done in some other place. The people investigating the dismantelt lab couldn't trace the source of the PtO2. 8)
I think PtO2 route is cheaper if you re-use your catalyst a few times. Besides that you only need some Methanol, MethylAmine and MDP2P ofcouse.
NaBH4 route is so slow. To many hours work for 1 batch. Not practical. Only if SWIM make it for himself.
