Reaction Steps
Thus obtained 5-acetyl-2-methylbenzenesulfonyl chloride was dissolved in 790 g of tetrahydrofuran, then 81 g of ammonia gas was added at a temperature below 10° C. 800 Grams of water was added to this reaction mixture, and tetrahydrofuran was removed by evaporation to crystallized 5-acetyl-2-methylbenzenesulfonamide. The crystals were collected by filtration, and dried to obtain 176.8 g (0.83M) of 5-acetyl-2-methylmethylbenzenesulfonamide. Melting point: 150.5°-151.5° C. The yield was 95% on the basis of 5-acetyl-2-methylbenzenesulfonyl chloride, and was 83% on the basis of N,N-diethylaniline salt of 5-acetyl-2-methylbenzenesulfonate.
