This compound was prepared using 85 mg (0.5 mmol) of 2-(phenyl-hydrazono)-malononitrile, which was derived from aniline (10 mL, 107 mmol) and malononitrile (161 mmol) as described in Example 8, and benzoic hydrazide (68 mg, 0.5 mmol). Solids had not formed after heating the reaction at 75° C. for 3 hrs, however, analysis of the reaction solution by TLC indicated that no starting material remained. The solution was allowed to cool to room temperature and the solvent was evaporated. The residue was dissolved in methanol and then precipitated by the addition of water. The resulting solid was isolated by filtration and dried to yield 20 mg (13%) of the title compound as an orange coloured solid.
