Reaction Conditions

Reaction Steps

To a solution of 5-methoxy-2-(4-[2-(methoxymethyloxy)ethyl]benzyl)phenyl β-D-glucopyranoside (0.053 g) in methanol (2.3 mL) was added p-toluenesulfonic acid monohydrate (0.032 g), and the mixture was stirred at 50° C. for 3 hours. After cooling to room temperature, to the reaction mixture was added triethylamine (0.5 mL), and the solvent was removed under reduced pressure. The residue was purified by preparative thin layer chromatography on silica gel (eluent: dichloromethane/methanol=6/1) to give 2-[4-(2-hydroxyethyl)-benzyl]-5-methoxyphenyl β-D-glucopyranoside (0.023 g).
