Versuchsvorschrift
To a solution of 4-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-6-hydroxy-3-(2-phenylethyl)benzofuran (45 mg) in methanol (3 mL) was added sodium methoxide (28% methanol solution, 0.015 mL), and the mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated under deduced pressure, and the residue was purified by column chromatography on silica gel (eluent: dichloromethane/methanol=10/1-5/1) to give the title compound (28 mg).
