Procedure

To a suspension of methyl 4-[(3-phenylpropanoyl)amino]benzoate (1.40 g, 4.94 mmol) in EtOH (16 mL) was added hydrazine hydrate (3.6 mL). After stirring for 16 h at reflux, the reaction mixture was cooled to rt and a white solid precipitated out. Filtration, washing with water (4×5 mL) and drying under vacuo at 60° C. for 2 hrs gave 1.08 g of the title compound (77%) as a white solid in 99.1% purity by HPLC (MaxPlot detection between 230 and 400 nm).
