실험 절차

4-benzyloxy-3-methoxybenzonitrile (4.78 g, 20 mmol) in acetic acid (10 ml) was slowly added to nitric acid (25 ml) at 20° C. to 30° C. The mixture was stirred at room temperature for 6 hours, basified (pH 10-11) with cooling (KOH 10N), extracted with methylene chloride, dried over MgSO4 evaporated. The solid was recristallysed in hot EtOAc, a yellow solid of title compound was obtained (3.62 g, 64%).
