To a mixture of N-(3-(4-chloro-1-methyl-1H-pyrazol-5-yl)-4-hydroxyphenyl)-3-(trifluoromethyl)benzamide (51 mg, 0.13 mmol) and potassium carbonate (27 mg, 0.20 mmol) in acetone (1 mL) was added 2-bromoacetamide (27 mg, 0.20 mmol). The resultant mixture was heated to 65° C. for 1 hour. Cooled to room temperature and partitioned between EtOAc and water. Layers were separated. The organic layer was washed with water (2×) and brine, dried (MgSO4) and reduced to give the title compound as a white solid (49 mg, 83%). LCMS m/z (%)=453 (M+H 35Cl, 100), 455 (M+H 37Cl, 30). 1H NMR (400 MHz, DMSO-d6) δ ppm 3.73 (s, 3H), 4.46-4.61 (m, 2H), 7.09 (d, J=9.09 Hz, 1H), 7.24 (s, 1H), 7.38 (s, 1H), 7.65 (s, 1H), 7.72 (d, J=2.78 Hz, 1H), 7.73-7.84 (m, 1H), 7.87 (dd, J=8.97, 2.65 Hz, 1H), 7.97 (d, J=6.57 Hz, 1H), 8.21-8.36 (m, 2H), 10.53 (s, 1H).
