The mixture of 4′-(4-chloro-5-(trifluoromethyl)pyrimidin-2-ylamino)-5′-methoxy-N,2′-dimethylbiphenyl-4-carboxamide (Step 1, 20 mg, 0.044 mmol), 5-methyl-1H-pyrazol-3-amine (4.3 mg, 0.044 mmol), Xantophos (5.0 mg, 0.009 mmol), paladium acetate (II) (1.0 mg, 0.004 mmol), and cesium carbonate (28.6 mg, 0.088 mmol) in 2.0 mL of THF is heated at 150° C. in a microwave reactor for 25 min. The reaction mixture is filtered, the filtrate is concentrated in vacuo, and purified by preparative RP-HPLC to afford 5′-Methoxy-N,2′-dimethyl-4′-(4-(5-methyl-1H-pyrazol-3-ylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)biphenyl-4-carboxamide; ESMS m/z 512.2 (M+H+).
