Hi all,
Everyone who is at least curious clandestine chemist enthusiast has heard of the Bromosafrole method from Pugsley, Uncle Fester, Wednesday and the like using the propenylbenzene of their choice. The process goes like this To 100 ml of chilled DMSO add 7.8ml conc. H2SO4 (i.e. drain cleaner). To this add 30g of NaBr. Stir well and repeatedly. Solution will turn orange as all the NaBr is turned into Na2SO4.
Add 5 ml of sassafrass oil. Or scale qty of everything up for more sassafrass. Let sit at room temp. Don't bother to filter out crystals, in case there is unreacted NaBr. In 1 or 2 days solution will proceed as in Fester's turning green, then purple, then gradually burgundy. The final mixture gets 500-1000ml of water added. The crude bromosafrole which settles to the bottom is separated without adding any organic solvent. If you cool it it gets pretty sticky and syrupy so the water layer can be just poured off.
Then you add 200ml of ethanol(Everclear) and a 5g tablet of hexamine camping fuel to start the Delepine reaction-, which you can either use a pipe bomb or reflux overnight. After the mixture has cooled, you just use the typical amine separation procedure i.e.. A/B, evaporate or distill off the useless chemicals and you get MDA as the end product after the crystallization process. Simple enough right?
Now to the debunction inquisition, First, can someone tell me, hopefully a skilled chemist, Does this method work? Can the delepine rxn be ran at room temp? Over how many days? Yield? Thanks to anyone who can help put this theory to bed once and for all.
