To a mixture of 22.1 g of acetyl cyanide and 16.3 g of diaminomaleonitrile were added dropwise a solution of 0.5 g of phosphorus pentoxide in 3 ml of methanol. The crude product thus obtained was recrystallized from aqueous methanol to obtain 6.3 g (26% yield) of α-cyanoethylidenediaminomaleonitrile.
