実験手順

A mixture of 8-isopropyl-8-aza-bicyclo[3.2.1]octan-3-one (CAS 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 sodium sulfate, 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+).
