実験手順

A solution of methyl 2-benzoyl-4,5-methylenedioxyphenylacetate (110 mg, 0.37 mmol) and hydrazine hydrate (30 μL, 0.53 mmol) in ethanol (15 mL) was refluxed for 5 days. The solvent was removed in vacuo and the resulting residue was separated by chromatography to yield the title compound (30 mg, 0.11 mmol, 29%), mp, 182°-184° C. 1H NMR (CDCl3) 8.59 (s, 1H), 7.60-7.41 (m, 5H), 6.83 (s, 1H), 6.63 (s, 1H), 6.03 (s, 2H), 3.46 (s, 2H). Anal. Calcd. for C16H12N2O3.0.25H2O: C, 67.48; H, 4.42; N, 9.84. Found C, 67.25; H, 4.21; N, 9.88.
