Procedure

To a solution (5 mL) of 5-(1-{[tert-butyl(dimethyl)silyl]oxy}ethyl)-2-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-3-methyl-1H-pyrrol-2-yl)pyridine (130 mg) in tetrahydrofuran (5 mL) was added tetrabutylammonium fluoride (1M tetrahydrofuran solution, 256 μL), and the mixture was stirred overnight at room temperature. 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 (83.0 mg, yield 79%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate-hexane (3:1, volume ratio). MS: 495 (MH+).
