Participants

Reaction Steps

To a solution of methyl glycerate (25.88 g, 215 mmol) and imidazole (22.0 g, 323 mmol, 1.5 eq) in tetrahydrofuran (250 mL) was added t-butyldiphenylsilyl chloride (53.0 mL, 204 mmol, 0.95 eq) at 0° C. After stirring for 18 h the reaction was quenched by the addition of saturated ammonium chloride and the aqueous phase was extracted with dichloromethane. The organic layer was dried with magnesium sulfate and evaporated under reduced pressure. The crude material was purified by flash chromatography with a mixture of hexanes and ethyl acetate (80:20) to give the compound (68.89 g) in 94% yield.
