실험 절차

Add sodium hydroxide (8.50 g, 220 mmol) in water (150 mL) to a solution of o-anisaldehyde (25.0 g, 180 mmol) and hydroxylamine hydrochloride (15.4 g, 220 mmol) in ethanol (150 mL) and water (150 mL) at room temperature and stir the mixture for 3 hours. Acidify the mixture to pH 6 with 1 N HCl solution and collect the solids by vacuum filtration to provide 2-methoxybenzaldehyde oxime (32.0 g, 99%).
