実験手順

To a sealed tube were added 2-(4-bromo-3-(trifluoromethyl)phenyl)-N-(5-phenylpyridin-2-yl)acetamide 46-7 (73 mg, 0.17 mmol), 2-methylpyridin-4-ylboronic acid (35 mg, 0.255 mmol), Pd(PPh3)4 (12 mg, 0.017 mmol), toluene (0.8 mL), ethanol (0.2 mL) and 2M Na2CO3 (0.5 mL). The reaction mixture was bubbled with nitrogen for 2 minutes and stirred at 90° C. for 10 hours. After cooled down to room temperature, the reaction mixture was diluted with ethyl acetate (50 mL) and washed with saturated NaHCO3 aqueous solution and brine. The organic phase was dried over Na2SO4 and concentrated to dryness by rotary evaporation. The crude product was purified by reverse phase HPLC to give 2-(4-(2-methylpyridin-4-yl)-3-(trifluoromethyl)phenyl)-N-(5-phenylpyridin-2-yl)acetamide 46 as white solid. MS m/z 448.1 (M+1); 1H NMR 400 MHz (CDCl3) δ 8.48-8.45 (m, 2H), 8.28 (d, 1H, J=8.4 Hz), 7.92 (dd, 1H, J1=8.4 Hz, J2=2.4 Hz), 7.75 (s, 1H), 7.61 (dd, 1H, J1=8.0 Hz, J2=1.2 Hz), 7.54-7.52 (m, 2H), 7.47-7.43 (m, 2H), 7.39-7.37 (m, 1H), 7.28 (d, 1H, J=7.6 Hz), 7.14 (s, 1H), 7.10 (d, 1H, J=5.2 Hz), 3.86 (s, 2H), 2.59 (s, 3H).
