실험 절차

A solution of 2-formyl-5-methoxy-benzoic acid (1.0 g, 6.10 mmol) and methyl hydrazine (0.481 mL, 1.5 eq.) in ethanol (15 mL) was stirred at 85° C. for 1.5 days. The solvent was removed and the solid was collected and washed with cold EtOH to give 7-methyl-2-methyl-2H-phthalazin-1-one (780 mg): MS m/z 191 (M+H).
