Method 1
To a well stirred, cooled mixture of 34g of 30% H202 (hydrogen peroxide) in 150g 80% HCO2H (formic acid) there was added, dropwise, a solution of 32.4g isosafrole in 120ml acetone at a rate that kept the reaction mixture from exceeding 40 deg C. This required a bit over 1 hour, and external cooling was used as necessary. Stirring was continued for 16 hours, and care was taken that the slow exothermic reaction did not cause excess heating. An external bath with running water worked well. During this time the solution progressed from an orange color to a deep red. All volatile components were removed under vacuum which yielded some 60g of a very deep residue. This was dissolved in 60ml of MeOH (methyl alcohol -- methanol), treated with 360ml of 15% H2SO4 (sulfuric acid), and heated for 3 hours on the steam bath. After cooling the mixture was extracted with 3x75ml Et2O (diethyl ether) or C6H6 (benzene). Its recommended that, the pooled extracts can washed -- first with H2O and then with dilute NaOH (sodium hydroxide). Then the solvent is removed under vacuum to afford 20.6g 3,4-methylenedioxyphenylacetone (3,4-methylenedioxybenzyl methyl ketone). The final residue may be distilled at 2.0mm/108-112 deg C, or at about 160 deg C at the water pump.
Add 23g 3,4-methylenedioxyphenylacetone to 65g HCONH2 (formamide) and heat at 190 deg for five hours. Cool, add 100ml H20, extract with C6H6 (benzene) and evaporate in vacuum the extract. Add 8ml MeOH (methyl alcohol -- methanol) and 75ml 15% HCl to residue, heat on water bath two hours and extract in vacuum (or basify with KOH and extract the oil with benzene and dry, evaporate in vacuum) to get 11.7 g 3,4-methylenedioxyamphetamine (MDA).
To produce MDMA substitute N-methylformamide for formamide in the above synthesis

Ik heb het 100 keer gelezen en kwam nog niet verder
plus weet nog amper of het wel een goed recept is ook
