Versuchsvorschrift

To a suspension of methyl 4-{[3-(1,3-benzodioxol-5-yl)propanoyl]amino}benzoate (200 mg, 0.61 mmol) in EtOH (3.5 mL) was added hydrazine hydrate (0.5 mL). After stirring for 15 hrs at reflux, the reaction mixture was cooled to rt and a white solid precipitated out. Filtration, washing with EtOH (2×1 mL) and water (3×1 mL), and drying under vacuo at 70° C. for 1 hr gave 130 mg of the title compound (65%) as a white solid in 95.5% purity by HPLC (MaxPlot detection between 230 and 400 nm).
