실험 절차

To a stirred solution of 1.0 g (2.19 mmole) of the title product of Example 2 in 30 ml of cold (ca.0° ) dichloromethane was added 0.463 g (2.19 mmole) of 81% m-chloroperoxybenzoic acid. After about ninety minutes, 5 ml of saturated aqueous sodium thiosulfate was added. The mixture was washed sequentially with three portions of saturated aqueous sodium bicarbonate and three portions of water. The organic phase was dried over sodium sulfate, filtered, and concentrated in vacuo to give tht title compound.
