To a mixture of tetrakis(triphenylphosphine)palladium (0) (0.12, 0.1 mmol), 2N sodium carbonate (5 mL, 10 mmol), [4-chloro-8-(trifluoromethyl)quinolin-3-yl](phenyl)methanone (from Example 1, 0.67 g, 2.0 mmol) in 20 mL of toluene and 5 mL of ethanol was added 3-aminobenzeneboronic acid (0.62 g, 4.0 mmol). The reaction mixture was heated to 80° C. for 1 hour, diluted with ethyl acetate, washed with water and dried over MgSO4. Removal of solvent under reduced pressure gave a crude product that was purified by silica gel chromatography eluting with ethyl acetate/hexanes (5% to 50%) to give the title compound as a pale yellow solid; MS (EI) m/z 393.3 (M+H)+; 1H NMR (DMSO-d6): δ 5.21 (s, 2H), 6.39 (d, J=8.8 Hz, 1H), 6.47 (s, 1H), 6.48 (d, J=9.4 Hz, 1H), 6.95 (t, J=9.4 Hz, 1H), 7.39 (t, J=7.5 Hz, 2H), 7.56 (t, J=8.7 Hz, 1H), 7.63 (d, J=8.2 Hz, 2H), 7.80 (t, J=7.8 Hz, 1H), 8.10 (d, J=8.6 Hz, 1H), 8.31 (d, J=6.7 Hz, 1H), 9.08 (s, 1H).
