To the mixture of 2,4-dichloro-5-(trifluoromethyl)pyrimidine (100 mg, 0.46 mmol) in 0.5 mL of DCE and 0.5 mL of t-BuOH is added zinc chloride (1.0 M in ether, 0.46 mL, 0.46 mmol), and stirred 30 min. 4′-amino-5′-methoxy-N,2′-dimethylbiphenyl-4-carboxamide (111 mg, 0.414 mmol) and triethylamine (46 mg, 0.46 mmol) are added sequentially, and the reaction is stirred at room temperature overnight. The precipitate is filtered, washed by MeOH, and dried in vacuo to afford 4′-(4-Chloro-5-(trifluoromethyl)pyrimidin-2-ylamino)-5′-methoxy-N,2′-dimethylbiphenyl-4-carboxamide as a white solid; ESMS m/z 451.1 (M+H+).
