Under an atmosphere of nitrogen, a flask was charged with 5-methyl-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (2.1 g, 8.2 mmol), 3-bromo-5-hydroxy-benzoic acid methyl ester (1.5 g, 6.2 mmol), potassium phosphate (2.8 g, 13 mmol), tetrakis(triphenylphosphine)palladium(0) (400 mg, 0.35 mmol), 1,4-dioxane (90 mL), and water (20 mL). The reaction mixture was stirred at 85° C. overnight. After cooling, the mixture was filtered through Celite and the filter cake was washed with EtOAc. The filtrate was concentrated and the residue was purified by silica gel column to afford the title compound.
