Reaction Steps
Compound (16) obtained in step (7) above (185 mg) was dissolved in N,N-dimethylformamide (3.7 ml), to which was then added sodium azide (37 mg), and the resultant mixture was stirred at room temperature for 1 hour to effect the desired reaction in order to convert the chloro group of compound (16) into azido group and thus to produce the titled compound (17). The reaction solution was concentrated and the residue obtained was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous sodium sulfate and then concentrated to yield a yellow syrup. This syrup was purified by silica gel column chromatography (developer solvent:toluene-ethyl acetate, 1:1), to give the titled compound (17) as a colorless solid (176 mg). Yield: 94%.
