실험 절차

To a solution of 2-(4-methoxybenzyl)phenyl β-D-glucopyranoside (0.075 g) in 2,4,6-trimethylpyridine (2 mL) was added ethyl chloroformate (0.04 mL) at room temperature. After the mixture was stirred at room temperature for 16 hours, a saturated aqueous citric acid solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by preparative thin layer chromatography on silica gel (eluent: dichloromethane/methanol=10/1) to give amorphous 2-(4-methoxybenzyl)phenyl 6-O-ethoxycarbonyl-β-D-glucopyranoside (0.032 g).
