Procedure

The damp 4-acetylbenzenesulfonyl chloride from 300 g. of sodium 4-acetylbenzenesulfonate is added in portions to a well-stirred, cooled solution of 500 ml. of bis(2-hydroxyethyl)amine in 750 ml. of water. The mixture is stirred at room temperature for 16 hours, cooled to 0-5° C. and the precipitate of 4-acetyl-N,N-bis(2-hydroxyethyl)benzenesulfonamide is collected by filtration and crystallized from water; m.p. 87.5°-89.5° C.
