Reaction Steps

2-Bromo-5-(trifluoromethyl)benzonitrile (5.5 g, 22 mmol), [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid ethyl ester (7.04 g, 22 mmol), potassium carbonate (7.6 g, 55 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.300 g, 0.25 mmol) were combined in DME (40 mL) and H2O (20 mL). The mixture was purged with N2, and then stirred at 85° C. for 36 hours. After standard work-up, the residue was purified by silica gel chromatography to give the title compound.
