Procedure
4-chloro-2-aminobenzenesulfonamide (20 g.) and 12 g. of 3-cyclohexene carboxaldehyde are combined in 150 ml. of acetonitrile and refluxed 41/2 hours. The precipitate which forms during refluxing and on cooling is collected by filtration and washed with cold acetonitrile. The crude (17.4 g) is recrystallized from dimethylformamide-water to give a white product melting at 252°-4°. Analysis calculated for C13H15ClN2O2S: C% 52.26, H% 5.06. Found: C% 52.39; H% 5.00.
