실험 절차

To a solution of 1-benzylpyrrolidin-3-one (1.0 g, 5.71 mmol) in pyridine (5 mL) is added hydroxylamine hydrochloride (0.59 g, 8.57 mmol). After stirring at 90° C. for 5 hours, the reaction mixture is diluted with ethyl acetate and washed with saturated sodium bicarbonate, water, and brine. The organic layer is dried over MgSO4, filtered, and filtrate concentrated to afford 1-benzylpyrrolidin-3-one oxime (1.11 g) as an oil. MS CI: m/z 191 (MH+).
