Reaction Steps

1-(3-methyl-4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)imidazolidin-2-one (0.100 g, 0.266 mmol), 1-iodo-3-(trifluoromethyl)benzene (0.050 mL, 0.35 mmol), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (0.012 g, 0.020 mmol), palladium (II) acetate (0.009 g, 0.013 mmol), and cesium carbonate (0.130 g, 0.399 mmol) were combined in dioxane under argon. The reaction vessel was sealed and the mixture was heated to 100 deg. C. for 48 h. The reaction was cooled to ambient temperature and diluted with dichloromethane, filtered, and concentrated in vacuo. The resulting material was adsorbed onto silica gel and purified by silica gel chromatography. The resulting material was further purified by reverse-phase HPLC using acetonitrile/water/TFA eluent to give 1-(3-methyl-4-(3-(2-(methylamino)pyrimidin-4-yl)pyridin-2-yloxy)phenyl)-3-(3-(trifluoromethyl)phenyl)imidazolidin-2-one as a white solid.
