Procedure

Into a 50-mL round bottom flask, was placed a solution of 4-chloro-2-(6-chloropyrimidin-4-yl)benzenamine (1.5 g, 6.25 mmol, 1.00 equiv) in N,N-dimethylformamide (30 mL), potassium carbonate (2.7 g, 19.54 mmol, 3.00 equiv), 3-(trifluoromethyl)benzylamine (1.7 g, 9.70 mmol, 1.50 equiv). The resulting solution was stirred overnight at 80° C. in an oil bath. The resulting mixture was concentrated under vacuum. The resulting solution was diluted with 20 mL of ethyl acetate. The resulting mixture was washed with 2×20 mL of water. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:2). This resulted in 1 g (42%) of N-(3-(trifluoromethyl)benzyl)-6-(2-amino-5-chlorophenyl)pyrimidin-4-amine as yellow oil
