Reaction Steps

(Z)-1-(2-Amino-1,2-dicyanovinyl)-3-(cyclohexylmethyl)urea. 2,3-Diaminomaleonitrile (0.119 g, 1.10 mmol) and (isocyanatomethyl)cyclohexane (0.140 g, 1.00 mmol) in tetrahydrofuran (2 mL) were reacted according to General Procedure A. Dichloromethane and hexanes were added to the solution and the resultant precipitate was filtered and dried to afford the title compound (0.200 g, 47%). MS (ESI) m/z 248.2 [M+1]+.
