Procedure

To a solution of tert-butyl 2-(2-(4-chloro-1-methyl-1H-pyrazol-5-yl)-4-(3-(trifluoromethyl)benzamido)phenoxy)acetate (0.460 g, 0.902 mmol) in CH2Cl2 (5 mL) was added water (0.5 mL) and trifluoroacetic acid (5 mL, 56 mmol). The resulting solution was stirred for 18 hours, reduced under vacuum, azeotroped with toluene, and triturated in ether to give the title compound as a white solid (0.290 g, 70.8%). LCMS m/z (%)=454 (M+H, 35Cl, 100), 456 (M+H, 37Cl, 30). 1H NMR (400 MHz, DMSO-d6) δ 3.72 (s, 3H) 4.70-4.84 (m, 2H) 7.11 (d, J=9.09 Hz, 1H) 7.63 (s, 1H) 7.72 (d, J=2.53 Hz, 1H) 7.79 (t, J=7.83 Hz, 1H) 7.87 (dd, J=9.22, 2.65 Hz, 1H) 7.97 (d, J=8.34 Hz, 1H) 8.26 (d, J=8.08 Hz, 1H) 8.29 (s, 1H) 10.52 (s, 1H) 13.10 (br. s., 1H).
