실험 절차

t-Butyidimethylsilylchloride (2.49 g, 16.5 mmol) was added to a solution of the alcohol 6 (3.6 g, 14.0 mmol) and imidazole (1.91 g, 28.0 mmol) in DMF (22 mL) at 23° C. The reaction was stirred for 16 h, diluted with Et2O and washed with 1 N HCl, saturated aqueous NaHCO3 and brine. The organic portion was dried (MgSO4), filtered and concentrated in vacuo. FCC (silica gel, 100% hex) afforded 5.18 g (63%) of the silyl ether 7 as a clear, colorless oil.
