Reaction Steps

To a 20 ml microwave vial with stir bar was added the 2-Chloro-6-(2,4-difluoro-benzylamino)-pyrimidine-4-carboxylic acid methyl ester, the pyrimidine from above (500 mg, 1.597 mmol), 5-trifluoromethylpyridine 3-boronic acid (566.9 mg, 2.076 mmol), palladium acetate (17.9 mg, 0.0798 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (98.2 mg, 0.239 mmol) and potassium carbonate (661 mg, 4.791 mmol). Reagents were suspended in dioxane (10 ml)/water (1 ml) and run in microwave reactor at 120° C. for 30 minutes. The reaction was cooled to room temperature, diluted with water (60 ml) and EtOAc (100 ml) and extracted with EtOAc (50 ml). The combined organic layer was washed with water (100 ml) and brine solution then dried over anhydrous sodium sulphate and evaporated. The residue was purified by column chromatography to get the title compound.
