Preparation of 3,4-Methylenedioxypropiophenone using Methanesulfonic Acid (MSA)
Reaction scheme: Synthesis: Methanesulfonic acid (MSA, 288g) and propionic anhydride (156g) were charged into a 1 liter reaction flask. The mixture was cooled to 0°C, and 122g of 3,4-methylenedioxybenzene (MDB) was added under stirring. The reaction mass was maintained at 0°C to 5°C for 4...- William Dampier
