Procedure

Compound (38) (60 mg) obtained in item (5) above was dissolved in N,N-dimethylformamide (1.2 ml), to which sodium azide (27 mg) was added and the mixture so obtained was stirred at room temperature for 2 hours. The resulting reaction solution was concentrated and the residue as formed was extracted with chloroform. The solution in chloroform thus formed was washed with water, dried over anhydrous sodium sulfate and then concentrated to afford the titled compound (39) (56 mg) as a syrup. Yield: 92%.
