실험 절차

To a solution of 3-(β-D-glucopyranosyloxy)-4-[(4-iso-propoxyphenyl)methyl]-5-methyl-1H-pyrazole (1.3 g) in tetrahydrofuran (30 mL) was added N-(benzyloxycarbonyloxy)-succinimide (1.6 g), and the mixture was heated under reflux overnight. The reaction mixture was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: dichloromethane/methanol=10/1) to give 1-(benzyloxycarbonyl)-3-(β-D-glucopyranosyloxy)-4-[(4-isopropoxyphenyl)methyl]-5-methylpyrazole (1.3 g).
