Procedure

A mixture of 5-[4-(cyclopropylsulfonyl)phenyl]-1-{5-[2-methoxy-1-(tetrahydro-2H-pyran-2-yloxy)ethyl]pyridin-2-yl}-6-(tetrahydro-2H-pyran-4-yl)hexane-1,4-dione (0.70 g), ammonium acetate (0.42 g) and acetic acid (5 mL) was stirred at 80° C. for 3 hr. The reaction mixture was neutralized with 8M aqueous sodium hydroxide solution, 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 (0.39 g, yield 69%) was obtained as a pale-yellow amorphous solid from a fraction eluted with ethyl acetate. MS: 511 (MH+).
