Procedure
To a suspension of methyl 4-[(4-heptylbenzoyl)amino]benzoate (823 mg, 2.33 mmol) in EtOH (10 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 619 mg of the title compound (75%) as a white solid in 99.4% purity by HPLC (MaxPlot detection between 230 and 400 nm).
