Procedure

To a suspension of methyl 4-[(4-cyanobenzoyl)amino]benzoate (680 mg, 2.43 mmol) in EtOH (8 mL) was added hydrazine hydrate (1.8 mL). After stirring for 15 h at reflux, the reaction mixture was cooled to rt and a white solid precipitated out. Filtration, washing with EtOH (1×2 mL) and water (2×2 mL), and drying under vacuo at rt for 72 hrs gave 432 mg of the title compound (64%) as a pale yellow solid in 94.2% purity by HPLC (MaxPlot detection between 230 and 400 nm).
