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 1,2-dichloroethane (5 mL) was added 2-(methylamino)ethanol (80 μL), and the mixture was stirred at room temperature for 30 min. To the reaction mixture was added sodium triacetoxyborohydride (280 mg), and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate, 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 (181 mg, yield 80%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate. MS: 524 (MH+).
