To a solution of ethylene glycol mono-2-chloroethyl ether (6.2 g, 50 mmol) in acetonitrile (150 mg) were added imidazole (6.77 g, 99.54 mmol) and t-butyldimethylsilyl chloride (11.25 g, 74.65 mmol) at room temperature. The reaction mixture was stirred overnight at the same temperature. After the reaction was completed, the mixture was filtered through a filter paper, and concentrated under reduced pressure. Then, the concentrate was subjected to flash chromatography on silica gel (n-hexane:ethyl acetate=9:1) to give the title compound (11.0 g, yield 92%) as a colorless oil.
