To a solution of 7-bromo-1-(2,6-difluorophenyl)-2H-quinolizin-2-one (100 mg, 0.3 mmole) was added 2,4-difluorophenol (0.06 ml, 0.6 mmole), 2,2,6,6-tetramethylheptane-3,5-dione (0.007 ml, 0.03 mmole), CuCl (15 mg, 0.15 mmole) and cesium carbonate (195 mg, 0.6 mmole) in NMP. The mixture was heated to 120° C. until the reaction completed. The mixture was diluted with ethyl acetate, washed with 1N HCl, 1N NaOH, brine, dried over MgSO4, and concentrated to yield crude material. The crude material was purified by silica gel chromatography (CH2Cl2/acetone) to yield the title compound.
