실험 절차

To a solution of 5-[4-(cyclopropylsulfonyl)phenyl]-1-(pyridin-2-yl)-6-(tetrahydro-2H-pyran-4-yl)hexane-1,4-dione (220 mg) in N,N-dimethylformamide (5 mL) was added ammonium acetate (190 mg), and the mixture was stirred at 100° C. for 1 hr. After cooling to 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, from a fraction eluted with ethyl acetate-hexane (3:1, volume ratio) to give a crude product. The obtained crude product was subjected to basic silica gel column chromatography, and the title compound (95 mg, yield 45%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate-hexane (1:1, volume ratio). MS: 437 (MH+).
