Reaction Steps

(Z)-1-(2-Amino-1,2-dicyanovinyl)-3-phenylurea. Phenyl isocyanate (0.700 g, 5.88 mmol) and 2,3-diaminomaleonitrile (0.600 g, 5.55 mmol) were reacted in acetonitrile according to General Procedure A. The material was triturated from acetonitrile and diethyl ether. The resultant solid was filtered and dried to give the title compound as an orange solid (0.95 g, 4.2 mmol, 76% yield) which was used directly in the next step.
