The compound (300 mg) obtained in Example 208 (2) and triethylamine (101 mg) were dissolved in tetrahydrofuran (30 ml), and thereto was added dropwise methanesulfonyl chloride (115 mg) under ice-cooling. The mixture was stirred at the same temperature for 1.5 hour, and thereto was further added N-methyl-4-chlorobenzylamine (1.04 g), and the mixture was further stirred for one hour. 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 [n-hexane:ethyl acetate (2:1)] to give the title compound (83 mg) as oil.
