Procedure

1-(2,3,4,6-Tetra-O-acetyl-β-D-glucopyranosyl)-3-(5-(4-aminophenyl)-2-thienylmethyl)-4-chlorobenzene (126 mg) obtained in Example 197-(1) was dissolved in dichloromethane (3 ml) and added thereto were methanesulfonyl chloride (48 mg) and pyridine (48 mg). The mixture was stirred at room temperature for 3.5 hours. To the mixture was added 2N hydrochloric acid aqueous solution at 0° C. and extracted with ethyl acetate. The organic layer was washed with water, aqueous sodium hydrogen carbonate solution and successively washed with brine. After drying over magnesium sulfate, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=1:1-1:2) to give 1-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-4-chloro-3-(5-(4-methylsulfonylaminophenyl)-2-thienylmethyl)benzene (154 mg) as yellow caramel. ESI-Mass m/Z 706/708 (M−H).
