실험 절차
To a solution of 4-[(4-isopropoxyphenyl)methyl]-5-methyl-3-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-1H-pyrazole (61 mg) in ethanol (3 mL) was added 1 mol/L aqueous sodium hydroxide solution (0.53 mL), and the mixture was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure, and the residue was purified by solid phase extraction on ODS (washing solvent: distilled water, eluent: methanol) to give 3-(β-D-glucopyranosyloxy)-4-[(4-isopropoxyphenyl)methyl]-5-methyl-1H-pyrazole (39 mg).
