5-MeO-MDMA (MMDMA) synthesis from Myristicine

[Jeffrey B.]

Myristicin to 5-MeO-MDMA (MMDMA) using HBr and Methylamine
(the graph shows CH2NH3 instead of CH3NH2 for some reason)

Can anybody please explain to me how this procedure would go? I can't seem to find any useful info online. I really need this procedure as I already have purchased moderate amounts of nutmeg oil a while ago. Thanks in advance!
