Procedure

Compound (39) obtained in step (5) above (170 mg) was dissolved in N,N-dimethylformamide (3.4 ml), to which was added sodium azide (45 mg). The resultant mixture was stirred at room temperature for 1 hour to conduct the reaction intended. The reaction solution obtained was concentrated and the residue was extracted with ethyl acetate. The extract was washed with water, dried over anhydrous sodium sulfate and concentrated to leave a yellow syrup. The syrup was purified by silica gel column chromatography (developer solvent: toluene-ethyl acetate, 1:2) to afford the titled compound (40) as a colorless solid (159 mg). Yield: 92%.
