Procedure

The compound (21) (177 mg) obtained in item (10) above was dissolved in N,N-dimethylformamide (3.5 ml), to which sodium azide (80 mg) was added, and the resulting mixture was stirred at room temperature for 2 hours. The reaction solution as formed was concentrated and the residue thus obtained was extracted with chloroform. The solution in chloroform was washed with water, dried over anhydrous sodium sulfate and concentrated to yield the titled compound (22) (153 mg) as a syrup. Yield: 85%.
