Reaction Steps
N-(2-bromo-6-chloro-4-(trifluoromethyl)benzyl)-2′,4′-dichloro-[1,1′-biphenyl]-4-amine (4.5 g, 8.8 mmol) and ethyl 3-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinamido)propanoate (3.1 g, 8.8 mmol), Pd(dppf)Cl2 (321 mg, 0.4 mmol), and 2 M K2CO3 (aq) (8.8 mL, 17.6 mmol) were dissolved in 1,4-dioxane (35 mL) and heated to 80° C. After 1 h the reaction was cooled to room temperature diluted with EtOAc and 4M aqueous NaCl, and the layers were separated. The aqueous layer was extracted with EtOAc and the combined organics were dried (Na2SO4), concentrated, and purified via column chromatography to yield the title compound.
