반응 단계

To a stirred solution of methyl β-D-glucopyranoside (5 g, 25.7 mmol) in 51 mL of dry DMF was added at room temperature imidazole (5.46 g, 80.2 mmol) followed by tert-butyldiphenylsilyl chloride (11.3 mL, 43.4 mmol). The solution was heated to 50° C. for 24 hours and the DMF was removed under reduced pressure. The reaction mixture was diluted with 200 mL of ethyl acetate and washed with H2O (1×100 mL), saturated aqueous NaCl (1×100 mL), and dried over magnesium sulfate. Concentration and flash chromatography (silica, 4% methanol in dichloromethane) provided pure target compound (9.82 g, 88%) as a white foam.
