実験手順

A mixture of 5-[4-(cyclopropylsulfonyl)phenyl]-6-(tetrahydro-2H-pyran-4-yl)-1-[5-(2,2,2-trifluoro-1-hydroxyethyl)-1,3-thiazol-2-yl]hexane-1,4-dione (0.45 g), ammonium acetate (0.31 g) and acetic acid (6 mL) was stirred at 80° C. for 3 hr. The reaction mixture was neutralized with 8M sodium hydroxide, and 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 (0.28, yield 65%) was obtained as a yellow amorphous solid from a fraction eluted with ethyl acetate-hexane (9:1, volume ratio). MS: 541 (MH+).
