Reaction Steps

4-{2-[4-(3-Benzyloxypropoxy)phenyl]ethyl}-3-(2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyloxy)-1H-pyrazolo-[3,4-b]pyridine (0.4 g) was dissolved in a mixed solvent of tetrahydrofuran (6 mL) and methanol (6 mL). To the solution was added 10% palladium-carbon powder (160 mg), and the mixture was stirred at room temperature under a hydrogen atmosphere for 3 hours. The insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (0.36 g).
