To a solution of N-(3-amino-5-bromophenyl)acetamide (3.25 g, 14.19 mmol) and 2-chloro-4-(trifluoromethyl)pyrimidine (2.054 mL, 17.03 mmol) in dioxane (8.5 mL) under nitrogen, was added pTsOH (2.70 g, 14.19 mmol). The reaction was stirred at 100° C. for 18 h, cooled to at room temperature. Solvent was removed under reduced pressure and the resultant residue was diluted with sat. NaH-CO3 (aq) and DCM. The organic was dried over sodium sulfate and was concentrated to dryness. Purified by flash chromatography (1:1 to 0:100 hexanes:ethyl acetate) to yield N-(3-bromo-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)acetamide (2.71 g, 7.22 mmol, 51%) as a beige powder. MS APCI: [M+H]m/z 377.0.
