실험 절차

To a mixture of 2-(4-bromo-2-fluorophenyl)acetic acid (360 mg, 1.545 mmol) in DCM (50 mL) was added 3-(1,1,1-trifluoro-2-methylpropan-2-yl)isoxazol-5-amine (300 mg, 1.545 mmol), HATU (881 mg, 2.317 mmol) and triethylamine (0.645 mL, 4.63 mmol). Then the mixture was stirred at 25° C. for 12 h. The mixture was washed with brine (50 mL), dried over Na2SO4, filtered, and concentrated to yield a yellow oil of 2-(4-bromo-2-fluorophenyl)-N-(3-(1,1,1-trifluoro-2-methylpropan-2-yl)isoxazol-5-yl)acetamide (600 mg, 1.1 mmol, 71% yield): 1H NMR (400 MHz, CDCl3) δ 8.09 (d, J=6.8 Hz, 1H), 7.34-7.29 (m, 1H), 7.21 (s, 1H), 6.64 (d, J=6.8 Hz, 1H), 6.43 (s, 1H), 3.75 (s, 2H), 1.52 (s, 6H); ES-LCMS m/z 409 (M+H).
