Iodomethane (0.063 mL, 1.007 mmol) and sodium iodide (151 mg, 1.007 mmol) were added to a solution of N-[3-(6-methoxypyridin-3-yl)phenyl]-4-(trifluoromethyl)pyrimidin-2-amine (109 mg, 0.315 mmol) in MeCN (3.1 mL) at room temperature under nitrogen. The mixture was heated to 45° C. for 72 hours, then cooled to room temperature and concentrated in vacuo. The residue was diluted with water and extracted with ethyl acetate (2×). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/hexanes) to afford 1-methyl-5-(3-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)pyridin-2(1H)-one as an off-white solid.
