Procedure

t-Butyldimethylsilyltrifluoromethanesulfonate (1.8 mL, 7.88 mmol) was added to a solution of triethylamine (2.2 mL, 15.8 mmol) and alcohol 4 (650 mg, 3.94 mmol) in CH2Cl2 (5.0 mL) at 0° C. The reaction was stirred for 1 h and then saturated aqueous NaHCO3 was added. The mixture was extracted with CH2Cl2. The organic portion was washed with brine, dried (Na2SO4), filtered and concentrated in vacuo. FCC (silica gel, 100% hexane) gave 1.7 g (100%) of the silyl ether 5 as a clear, colorless oil.
