The compound (3.45 g) obtained in the above (2) and triethylamine (976 mg) were dissolved in DMF (35 ml), and thereto was added dropwise methanesulfonyl chloride (0.75 ml) under ice-cooling. The mixture was stirred at the same temperature for 2 hours, and thereto was added sodium azide (627 mg), and the mixture was further stirred for 2 hours. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated brine, dried over sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography [chloroform:methanol (98:2)] to give the title compound (3.48 g) as oil.
