Procedure

1-(β-D-Glucopyranosyl)-4-chloro-3-(5-(4-formylphenyl)-2-thienylmethyl)benzene (84 mg) obtained in Example 249 was dissolved in a mixture of ethanol (2 ml)-tetrahydrofuran (2 ml) and added thereto was sodium borohydride (7 mg). The mixture was stirred at room temperature for 1 hour. The mixture was quenched by 2N hydrochloric acid aqueous solution (3 drops) at 0° C., and the solvents were evaporated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:methanol=9:1) to give the desired 1-(β-D-glucopyranosyl)-4-chloro-3-(5-(4-hydroxymethylphenyl)-2-thienylmethyl)benzene (82 mg) as colorless foam. APCI-Mass m/Z 494/496 (M+NH4).
