Procedure
12.5 ml of 25% ammonia were added at approx. 60° C. to a solution of 11,8 g of 2-cyano-3-chlorobenzenesulphonylchloride in 20 ml of dioxane. After heating on a steam bath for 30 minutes the reaction mixture was cooled and diluted with water. The resulting crystalline product was sucked off, washed with water and dried. The desired product was obtained in a yield of 8.9 g. After recrystallization from ethanol, the product melted at 261°-263° C.
