Reaktionsschritte

To a solution of 1-(2-benzyloxyethyl)-4-[(4-ethylphenyl)methyl]-3-(β-D-glucopyranosyloxy)-5-methyl-1H-pyrazole (0.012 g) in ethanol (2 mL) was added a catalytic amount of 10% palladium-carbon powder, and the mixture was stirred at room temperature under a hydrogen atmosphere for 30 minutes. Insoluble materials were removed by filtration, and the solvent was removed under reduced pressure to give 4-[(4-ethylphenyl)methyl]-3-(β-D-glucopyranosyloxy)-1-(2-hydroxyethyl-5-methyl-1H-pyrazole (0.011 g).
