Reaction Steps

Cesium carbonate (815 mg, 2.50 mmol) was added to a solution of N-(3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-hydroxyphenyl)-3-(trifluoromethyl)benzamide (396 mg, 1.00 mmol) and 2-methyl-2-nitropropyl methanesulfonate (276 mg, 1.40 mmol) in DMA (2.0 mL), and the mixture was stirred at 160° C. After 1 hour, the mixture was allowed to cool to room temperature and poured into water, and the resulting suspension was extracted with dichloromethane. The extract was dried with sodium sulfate, filtered, and evaporated to dryness. The crude product was purified by flash chromatography (ethyl acetate-hexanes 1:2) to afford the title compound (338 mg, 68%) as a yellow oil. LCMS m/z (%)=499.5 (M+H, 37Cl 31.5), 497.4 (M+H, 35Cl 100.0). 1H NMR (400 MHz, CDCl3) δ 1.51 (s, 3H) 1.57 (s, 3H) 3.64 (s, 3H) 4.01 (d, J=9.85 Hz, 1H) 4.49 (d, J=9.85 Hz, 1H) 7.08 (d, J=8.84 Hz, 1H) 7.49 (d, J=2.53 Hz, 1H) 7.51 (s, 1H) 7.65 (t, J=7.71 Hz, 1H) 7.79-7.89 (m, 3H) 8.07 (d, J=7.83 Hz, 1H) 8.13 (s, 1H).
