Procedure

To a solution of 6-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)pyridine-3-carbaldehyde (200 mg) in tetrahydrofuran (5 mL) was added methylmagnesium bromide (3M diethyl ether solution, 450 μL) at 0° C., and the mixture was stirred overnight at room temperature. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and the title compound (83.0 mg, yield 40%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate. MS: 481 (MH+).
