Procedure

To a solution of 5-(5-{1-[4-(methylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)-1,3,4-thiadiazole-2-carbaldehyde (700 mg) in tetrahydrofuran (10 mL) was added methylmagnesium bromide (1M tetrahydrofuran solution) (3.46 mL) and the mixture was stirred at room temperature for 10 min. Saturated aqueous ammonium chloride solution 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 (460 mg, yield 63%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate-methanol (9:1, volume ratio). MS: 462 (MH+).
