Versuchsvorschrift

To a solution of 1-[5-(2,2-dimethyl-1,3-dioxolan-4-yl)pyridin-2-yl]-5-[3-fluoro-4-(methylsulfanyl)phenyl]-6-(tetrahydro-2H-pyran-4-yl)hexane-1,4-dione (500 mg) in acetic acid (5 mL) was added ammonium acetate (1.20 g), and the mixture was stirred at 110° C. for 45 min. 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 to give a crude product (400 mg). To a solution of the obtained crude product (400 mg) in tetrahydrofuran (5 mL) was added 1M hydrochloric acid (5 mL), and the mixture was stirred at 50° C. for 3 hr. The reaction mixture was diluted with ethyl acetate, and washed with saturated aqueous sodium hydrogen carbonate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated to give the title compound (367 mg, quantitatively) as a pale-brown amorphous solid. MS: 457 (MH+).
