실험 절차
4.10 ml (81.2 mmol) of hydrazine was added to an ethanol solution (100 ml) of 17.33 g (67.6 mmol) of the obtained 2-(4-methoxyphenyl)-benzoic acid, and the reaction liquid was stirred at 60° C. for 4 hours. The reaction liquid was concentrated under reduced pressure, and the resulting solid was washed with diethyl ether to obtain 9.46 g (yield: 55%) of 4-(4-methoxyphenyl)-2H-phthalazin-1-on as a white solid.
