Procedure

Compound (37) (80 mg) obtained in item (4) above was dissolved in dichloromethane (4 ml), to which was added at 5° C. a 1.25M hydrogen chloride solution (0.2 ml) in diethylether and the mixture obtained was allowed to undergo the reaction at that temperature overnight. The resulting reaction solution was washed with water, and the organic layer was dried over anhydrous sodium sulfate and then concentrated to give the titled compound (38) (61 mg) as a syrup. Yield: 75%.
