Procedure

To a solution of 5-carbamoyl-2-(4-ethylbenzyl)phenyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside (0.13 g) in methanol (3 mL) was added sodium methoxide (28% methanol solution; 0.043 mL), and the mixture was stirred at room temperature for 30 minutes. The reaction mixture was purified by column chromatography on (benzenesulfonylpropyl) silica gel (eluent: methanol). To the obtained compound was added diethyl ether, and the resulting precipitates were collected by filtration and dried under reduced pressure to give 5-carbamoyl-2-(4-ethylbenzyl)phenyl β-D-glucopyranoside (0.079 g).
