Reaction Steps

To a mixture of 2-(4-bromo-2-fluorophenyl)acetic acid (90 mg, 0.386 mmol) in DCM (10 mL) was added 6-ethoxy-5-(trifluoromethyl)pyridin-3-amine (88 mg, 0.425 mmol), DIEA (0.135 mL, 0.772 mmol) and HATU (220 mg, 0.579 mmol). The mixture was stirred at 25° C. for 16 h. The mixture was diluted with H2O and extracted with DCM. The combined organic extract was washed with brine, dried over MgSO4, filtered and concentrated. The crude material was purified by preparative TLC (PE/EA=1:1, Rf=0.6) to yield a light yellow oil of 2-(4-bromo-2-fluorophenyl)-N-(6-ethoxy-5-(trifluoromethyl)pyridin-3-yl)acetamide (120 mg, 0.228 mmol, 59.0% yield): 1H NMR (400 MHz, CD3OD) δ 8.49 (d, J=2.0 Hz, 1H), 8.27 (d, J=2.5 Hz, 1H), 7.39-7.34 (m, 3H), 4.47 (m, 2H), 1.21 (t, J=6.5 Hz, 3H); ES-LCMS m/z 421.0 (M+H).
