実験手順
4-Chloromethylbenzaldehyde (11.93 g, 77.17 mmol) was dissolved in ethanol (200 ml), hydroxylamine hydrochloride (10.73 g, 154.41 mmol) was added, and the mixture was stirred at 50° C. for 3 hours. Ethanol was evaporated under reduced pressure, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (12.69 g, 97%).
