Imidazole → Silane, [(8-bromooctyl)oxy](1,1-dimethylethyl)dimethyl-

Participants

Reaction Steps

A solution of 8-bromooctan-1-ol (2.15 g, 10.3 mmol), t-butyldimethylsilyl chloride (1.7 g, 11.3 mmol) and imidazole (1.7 g, 25.0 mmol) in dimethylformamide (4 ml) was stirred at room temperature under argon for 48 hours. The reaction was quenched by the addition of water and extracted with hexane. The organic layer was washed with 5% hydrochloric acid, 5% sodium bicarbonate, water, saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated to give a colorless oil. Purification by flash chromatography (silica, 0 to 2% ethyl ether/hexane) gave the desired protected alcohol.
