Procedure
To a solution of 5-chloro-2-thiophenesulfonamide 1.9 g, 10 mmole) in 10 ml of acetone was added aqueous sodium hydroxide (10 ml of 1N. 10 mmole) followed by a solution of 4-chlorophenyl isocyanate (1.54 g, 10 mmole) dissolved in 10 ml of acetone. This mixture was stirred at room temperature overnight. The reaction mixture was concentrated under vacuum and acidified with aqueous hydrochloric acid (10 ml of 1N, 10 mmole). The precipitate was filtered and the residue washed with hexanes and water. The solid was dried in a vacuum oven.
