Reaction Steps

To a solution of 4-(2-phenylethyl)-3-(2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyloxy)-1H-pyrazolo-[3,4-b]pyridine (0.26 g) in methanol (5 mL) was added sodium methoxide (28% methanol solution, 0.067 mL), and the mixture was stirred at 50° C. for 5 hours. To the reaction mixture was added acetic acid (0.04 mL), and the resulting mixture was purified by column chromatography on silica gel (eluent: dichloromethane/methanol=10/1-5/1) to give the title compound (91 mg)
