Reaction Steps

(E)-N-(4-Chloro-3-(trifluoromethyl)phenyl)-3-(3-hydroxyphenyl)-2-methylacrylamide (1.0 g, 2.81 mmol), 4-chloropicolinonitrile (428 mg, 3.09 mmol) and cesium carbonate (2.75 g, 8.43 mmol) were combined and stirred in DMF. The reaction mixture was heated at 100° C. overnight and then cooled to rt. The mixture was filtered to remove cesium carbonate, the collected precipitate was washed with EtOAc, and the combined filtrate was concentrated. Purification by column chromatography (SiO2, 0-80% EtOAc in hexanes) provided the title compound (883 mg). LCMS, FA: Rt=2.15 min, [MH+ 458.0].
