실험 절차
To a solution of 2-chlorobenzoyl chloride (8 g, 46 mmol) in dichloromethane (200 mL) at 0° C. was added N,O-dimethylhydroxylamine hydrochloride (4.9 g, 50 mmol) followed by pyridine (11 mL, 137 mmol). The mixture was stirred at room temperature for 16 hours. Water was added to the reaction mixture and organic layer was washed with brine, dried over magnesium sulfate and concentrated. Purification by chromatography on silica gel gave 2-chloro-N-methoxy-N-methylbenzamide (21) (7.8 g, 39.2 mmol, 85%) as clear oil.
