Procedure
To a solution of 4-({[tert-butyl(diphenyl)silyl]oxy}methyl)-2-(5-{1-[4-(methylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridine (870 mg) in tetrahydrofuran (10 mL) was added tetrabutylammonium fluoride (1M tetrahydrofuran solution, 1.54 mL), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was diluted with ethyl acetate and washed with water. The ethyl acetate layer was washed with saturated aqueous sodium hydrogen carbonate and saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (533 mg, yield 95%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate. MS: 441 (MH+).
