Procedure

To a solution of 1-(cyclopropylmethyl)-3-(β-D-glucopyranosyloxy)-4-[(4-isopropoxyphenyl)methyl]-5-methyl-1H-pyrazole (0.050 g) in 2,4,6-trimethylpyridine (1 mL) was added ethyl chloroformate (0.035 g), and the mixture was stirred at room temperature overnight. Citric acid monohydrate (3.3 g) and water were added to the reaction mixture, and the mixture was purified by solid phase extraction on ODS (washing solvent: distilled water, eluent: methanol), and successively by column chromatography on silica gel (eluent: dichloromethane/methanol=10/1) to give 1-(cyclopropylmethyl)-3-(6-O-ethoxycarbonyl-β-D-glucopyranosyloxy)-4-[(4-isopropoxyphenyl)methyl]-5-methyl-1H-pyrazole (0.043 g).
