実験手順
To a solution of 5-(5-{1-[4-(cyclopropylsulfonyl)phenyl]-2-(tetrahydro-2H-pyran-4-yl)ethyl}-1H-pyrrol-2-yl)-1,3,4-thiadiazole-2-carbaldehyde (300 mg) in tetrahydrofuran (20 mL) were added morpholine (83 mg), sodium triacetoxyborohydride (270 mg) and triethylamine (177 μL) and the mixture was stirred at room temperature for 18 hr. Saturated aqueous sodium hydrogen carbonate 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 basic silica gel column chromatography, and the title compound (141 mg, yield 41%) was obtained as a colorless amorphous solid from a fraction eluted with ethyl acetate. MS: 543 (MH+).
