실험 절차

To a stirred solution of sodium hydrogen carbonate (2.73 g, 32.5 mmol) in water (50 mL) was added hydroxylamine hydrochloride (2.30 g, 33.2 mmol) in portions over 30 min. The resultant solution was added to a vigorously stirred suspension of 2-fluoro-3-methoxybenzaldehyde (5.00 g, 32.5 mmol) in ethanol (45 mL) and the reaction mixture stirred at RT for 16 hr. The resultant precipitate was removed by filtration and washed with water (3×100 mL) and then allowed to dry in air to afford 2-fluoro-3-methoxybenzaldehyde oxime (14) (4.69 g, 85%) as a white crystalline solid: m/z 170 (M+H)+ (ES+).
