Procedure

To (4-chloro-8-trifluoromethyl-quinoline-3-yl)-phenyl-methanone (150 mg, 0.448 mmol), 3,5-difluorophenyl boronic acid (141 mg, 0.895 mmol), tetrakis(triphenylphosphine) palladium (52 mg, 0.045 mmol), sodium carbonate (50 mg, 1.41 mmol) in water (750 ml), glyme (2 ml), and ethanol (350 ml), was subjected to micro wave conditions (140° C., 300 watts, 300 sec.). The resulting dark red-brown mixture was filtered concentration in vacuo. Reverse phase gradient HPLC (CH3CN, H2O) afforded the title compound as a yellow powder (88 mg, 48%). MS (ESI) m/z 414; HRMS: calcd for C23H12F5NO, 413.0839; found (ESI, [M+H]+), 414.0911.
