실험 절차

To a suspension of methyl 4-{[(4-chlorobenzoyl)amino]methyl}benzoate (303 mg, 1.0 mmol) in EtOH (6 mL) was added hydrazine hydrate (1.0 mL). After stirring for 15 h at reflux, the reaction mixture was cooled to rt and a white solid precipitated out. Filtration, washing with water (3×2 mL) and drying under vacuo at 60° C. for 2 hrs gave 213 mg of the title compound (70%) as a white solid in 96.5% purity by HPLC (MaxPlot detection between 230 and 400 nm).
