実験手順

To a reaction vessel charged with N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-bromo-3-(trifluoromethyl)phenyl)acetamide 192-1 (300 mg, 0.62 mmol), 2-methylpyridin-4-ylboronic acid 172-1 (127 mg, 0.93 mmol) and Pd(PPh3)4 (36 m g, 0.03 mmol) was added toluene (6 mL), ethanol (2 mL) and saturated sodium carbonate (2 mL). The reaction mixture was flushed with nitrogen and heated to 110° C. for 10 hours. After the reaction was cooled down to room temperature, it was partitioned between ethyl acetate and saturated NaHCO3 and the organic phase was washed with brine and dried over Na2SO4. The solvent was removed by rotary evaporation and the residue was purified by reverse phase HPLC to give N-(5-(4-acetylpiperazin-1-yl)pyridin-2-yl)-2-(4-(2-methylpyridin-4-yl)-3-(trifluoromethyl)phenyl)acetamide 172. MS m/z 498.2 (M+1). 1H NMR 400 MHz (DMSO-d6) δ10.67 (s, 1H), 8.66 (d, 1H), 8.05 (m, 1H), 7.94 (m, 2H), 7.75 (d, 1H), 7.52 (s, 1H), 7.45 (m, 3H), 3.88 (s, 2H), 3.58 (b, 4H), 3.14 (b, 2H), 3.09 (b, 2H), 2.61 (s, 3H), 2.05 (s, 3H).
