Procedure

4.0 G. of 4-amino-3,5-dibromobenzenesulfonyl chloride is added to a solution of 34 ml. of isopropylamine in 30 ml. of water. The resultant solution is stirred overnight at room temperature and poured onto 250 ml. of an ice/water mixture. The precipitate is filtered, washed with water and dried. The dried filtrate is recrystallized from isopropanol affording pure 4-amino-3,5-dibromo-N-isopropylbenzenesulfonamide, m.p. 181° to 183° C.
