1-(β-D-glucopyranosyl)-4-chloro-3-(5-(1H-tetrazol-5-yl)-2thienylmethyl)benzene (140 mg) obtained in Example 181 was dissolved in dimethylformamide (5 ml) and added thereto were methyl iodide (100 μl) and potassium carbonate (220 mg). The mixture was stirred at room temperature overnight. The reaction solution was poured into water and the mixture was extracted with ethylacetate. The extract was washed with brine and dried over sodium sulfate, and the solvent was evaporated under reduced pressure to give the desired 1-(β-D-glucopyranosyl)-4-chloro-3-(5-(2-methyl-2H-tetrazol-5-yl)-2-thienylmethyl)benzene as colorless powder. APCI-Mass m/Z 470/472 (M+NH4).
