반응 단계
A solution of 28 g of crude 5-bromo-1-pentanol in 144 ml of tetrahydrofuran is mixed with 24 g of imidazole. Then, a solution of 30.3 g of tert-butyldimethylchlorosilane in 46 ml of tetrahydrofuran is added in drops, and it is stirred for 4 hours at room temperature. The reaction mixture is poured into water, shaken out with diethyl ether, the organic phase is washed 4 times with water, dried on sodium sulfate and concentrated by evaporation. The crude product is chromatographed on silica gel with hexane/diethyl ether. 42 g of the title compound is obtained as a colorless liquid.
