To a solution of 3-(1-methyl-1H-pyrazol-5-yl)-4-(2-(pyrrolidin-1-yl)ethoxy)benzenamine (0.029 g, 0.10 mmol) in CH2Cl2 (1.5 mL) was added 3-fluoro-4-(trifluoromethyl)benzoyl chloride (0.018 mL, 0.12 mmol) and triethylamine (0.018 mL, 0.13 mmol). The reaction was stirred for 1 h, and concentrated and purified by RP-HPLC. Lyophilization afforded a TFA salt as a brown oil (0.042 g, 88%). LCMS m/z (%)=477 (M+H, 100). 1H NMR (400 MHz, DMSO-d6) δ: 10.55 (s, 1H), 8.07-7.95 (m, 3H), 7.88 (dd, J=2.6, 9.0 Hz, 1H), 7.73 (d, J=2.6 Hz, 1H), 7.49 (d, J=1.8 Hz, 1H), 7.27 (d, J=9.0 Hz, 1H), 6.31 (d, J=1.8 Hz, 1H), 4.33-4.29 (m, 2H), 3.69 (s, 3H), 3.58-3.52 (m, 2H), 3.35-3.25 (m, 2H), 2.92-2.81 (m, 2H), 1.95-1.85 (m, 2H), 1.80-1.69 (m, 2H).
