Reaktionsschritte

To a suspension of methyl 4-{[4-(hexyloxy)benzoyl]amino}benzoate (856 mg, 2.41 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 681 mg of the title compound (80%) as a white solid in 99.7% purity by HPLC (MaxPlot detection between 230 and 400 nm).
