Procedure
To a suspension of methyl 3-[(4-cyanobenzoyl)amino]benzoate (762 mg, 2.72 mmol) in EtOH (8 mL) was added hydrazine hydrate (1.79 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 (3 mL) and water (3×3 mL) and drying under vacuo at 60° C. for 2 hrs gave 518 mg of the title compound (68%) as a white solid in 98.8% purity by HPLC (MaxPlot detection between 230 and 400 nm).
