Reaction Steps

21.3 Grams (0.1M) of 5-acetyl-2-methylbenzenesulfonamide was dissolved in 180 g of methanol, while the resulting solution was kept at 35°-40° C., 16.0 g (0.1M) of bromine was added dropwise by taking 1.5 hours. The reaction mixture was stirred for 10 minutes after the dropwise addition, 80 g of water was added to the reaction mixture and the whole reaction mixture was stirred for further 30 minutes at room temperature. A part of methanol-water was removed by evaporation, then the crystals formed were collected by filtration, washed with water and dried to obtain 28.0 g of 5-bromoacetyl-2-methylbenzenesulfonamide in the form of white crystals. Melting point: 146.5°-147.5° C. Yield: 95.9%.
