4-chloro-6-(2,2,2-trifluoro-1-(3′-fluorobiphenyl-4-yl)ethoxy)pyrimidin-2-amine (320 mg, 0.806 mmol), methyl 2-oxo-2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenylamino)acetate (320 mg, 0.95 mmol), dichlorobis(triphenylphosphine)palladium (79 mg, 0.11 mmol), and Na2CO3 (212 mg, 2.0 mmol) were added to a mixture of ethanol (10 mL) and water (10 mL) in a round-bottom flask. The flask was heated to reflux for 8 hours. The reaction mixture was cooled and solvent was removed. The residue was dissolved in 10 mL of 0.5 M NaOH solution, filtered, and the filtration was extracted with EtOAc. The organic portion was dried and the solvent was removed to get 250 mg of the above-named compound. 1H NMR (300 MHz, CD3OD): δ δ 7.90 (m, 2H), 7.77 (s, 3H), 7.60 (m, 2H), 7.44 (m, 2H), 7.22 (m, 1H), 7.10 (m, 1H), 7.05 (s, 1H), 6.83 (m, 1H), 5.09 (m, 1H), 3.67 (s, 3H); M+1=541.
