Product 1

HCID 740654-Acetylbenzenesulphonamide

Procedure

The damp 4-acetylbenzenesulfonyl chloride from 50 g. of sodium 4-acetylbenzenesulfonate is added in portions, with stirring, to 500 ml. of concentrated aqueous ammonia. The mixture is stirred at room temperature for 16 hours, cooled, and the precipitated 4-acetylbenzenesulfonamide removed by filtration and crystallized from aqueous ethanol/acetone; m.p. 177°-179° C.
