실험 절차

The compound (20) (21.8 mg) obtained in item (9) above was dissolved in dichloromethane (1 ml), and to the resulting solution was added a 1.25M hydrogen chloride solution (0.05 ml) in diethylether at 5° C., and the mixture so obtained was allowed to stand at that temperature overnight. The resulting reaction solution was washed with water and the organic layer obtained was dried over anhydrous sodium sulfate and concentrated to give the titled compound (21) (18.0 mg) as a syrup. Yield: 81%.
