I guess the easiest route to MDMA would be Wacker oxidation with DMF, followed by MM Al-Hg with nitromethane. Then you don't have to make MeAm.HCl.
Wacker with DMF is easier, uses less p-benzo, do not require heating and yields more. DMF aquisition is a bit difficult. If you can't get it use MeOH.
Regarding aquisition, a few years ago I drove to a nearby state and was able to purchase DMF, paid cash, no papers. The guys who sold me that have a small internet business, they operate from their home, I didn't know it when I went there. Anyway they sold it to me. Recently I placed an order with them, they said twice please confirm your address by phone, I did it, they said they will ship it, then nothing. I am sure they decided not to sell it to me. Then I just walked to my nearby chemical supply store, asked "Do you have any N,N-dimethylformamide" and I know they usually do not carry it, but just in case ..., and the lady said, "Yes, we have one gallon and seven pints." I bought two pints, paid cash, and left. They are a respectable science and chemicals store but also bee friendly place, not so much for the other guys. If you deal with them, be careful, I think they do not sell to individuals or don't like to. They are in a western state, the name of their business has a word similar to "hemp". They have also some interesting stuff other than DMF, they are NOT a chemical supply store.
