Participants

Reaction Steps

A solution of freshly distilled p-chlorophenyl isocyanate (1.38 g.) in 10 ml. chloroform is added at room temperature in one portion to a solution of 1-isobutyl-3-(m-aminophenyl)thiourea (2.0 g.) in chloroform (30 ml.). The product precipitates rapidly and is filtered off after several hours. The filter cake is washed with chloroform and dried to give 1-(3-p-chlorophenylureido)-3-(3-isobutylthioureido)-benzene, m.p. 195°-196° C.
