실험 절차

A mixture of 8-isopropyl-8-aza-bicyclo[3.2.1]octan-3-one (CAS no: 3423-28-7) (20.0 g, 120 mmol) in ethanol (500 mL) and pyridine (14.5 mL, 179 mmol) with hydroxylamine hydrochloride (8.81 g, 127 mmol) was refluxed for 16 h. Cooled to 23° C., the precipitate was filtered off, washed with diethyl ether leaving a solid, which was partitioned between dichloromethane and sodium carbonate solution, the organic layers dried over Na2SO4, filtered and the solvents evaporated to give the title compound as a white solid. (17.7 g, 82%); MS: m/e=183.2 (M+H+).
