Reaction Steps
A solution of tert-butyldimethylsilyl chloride (1.5 g, 9.9 mmol) in anhydrous N,N-dimethylformamide (5 mL) was added, dropwise, at 0° C., to a solution of 1,4-cyclohexanediol (1.0 g, 8.6 mmol) and imidazole (1.5 g, 22.0 mmol) in anhydrous tetrahydrofuran (5 mL). After completion of the addition brine was added and the resulting mixture was extracted 3 times with ethyl acetate. The combined organic extracts were washed with water and brine, dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure. The crude residue was purified on a silica gel plug (hexane/EtOAc, 80/20) to afford 1.3 g (66% yield) of 4-(tert-butyl-dimethyl-silanyloxy)-cyclohexanol as a colorless oil.
