Reaction Steps

4 g of iodobenzene-sulfonamide and 40 ml of acetone were mixed together and 3.92 g of potassium carbonate were added. The reaction was heated to reflux and 1.46 ml of n-propyl isocyanate were added. The medium was maintained at reflux for 2 hours, and after concentrating, 200 ml of water were added. Then, while cooling the reaction mixture to approximately 0°-5° C., a 2N hydrochloric acid solution was added until a pH of 3 was obtained. After crystallizing from acetone-isopropyl ether, 4.9 g of the expected product melting at 211°-212° C. were obtained.
