Procedure

A stirred suspension of 5.0 g (0.02 mol) of 2,6-bis(methylthio)benzenesulfonamide, 8.3 g (0.06 mol) potassium carbonate and 3.4 ml (0.03 mol) n-butyl isocyanate was heated at reflux for four hours. After stirring at 25° C. overnight, the mixture was poured into ice and 30 ml 10% HCl. The resulting precipitate was collected, washed several times with water and air dried to provide 6.5 g of the title compound, m.p. 151°-154°.
