Procedure

To a solution of 1-(2-hydroxyethyl)-4-[2-(4-hydroxy-phenyl)ethyl]-3-(2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyloxy)-1H-indazole (0.31 g) in methanol (6 mL) were added water (0.6 mL) and lithium hydroxide monohydrate (0.16 g), and the mixture was stirred at room temperature for 8 hours. The reaction mixture was concentrated under reduced pressure, and the residue was dissolved in water. To the solution was added acetic acid (0.45 mL), and the resulting mixture was purified by solid phase extraction on ODS (washing solvent: distilled water, eluent: methanol) to give the title compound (0.14 g)
