Reactions of 4-(Dicyanomethylene)-3-methyl-1-phenyl-2-pyrazolin-5-one Towards Amines and Phenols

3-Methyl-1-phenyl-2-pyrazoline-4,5-dione (3) condenses readily with malononitrile in refluxing ethanol to yield 4-(dicyanomethylene)-3-methyl-1-phenyl-2-pyrazolin-5-one (4).Compound 4 readily reacts with aliphatic, aromatic, and heterocyclic amines to yie
