Procedure

2-Bromo-5-trifluoromethyl-benzaldehyde (4.152 g, 16.41 mmol), [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]acetic acid methyl ester (4.988 g, 16.41 mmol), and potassium carbonate (5.67 g, 41.03 mmol) were combined in DME (40 mL) and H2O (20 mL) under N2. The mixture was purged with N2, and then tetrakis(triphenylphosphine)palladium(0) (1.9 g, 1.64 mmol) was added, and the reaction was heated to 90° C. for 10 hours. Once no starting material was seen by analytical LCMS, the mixture was cooled to room temperature and diluted with CH2Cl2 and H2O. The aqueous layer was separated and extracted with CH2Cl2, and the combined organic layers were dried over MgSO4, filtered, and concentrated. The residue was purified by silica gel chromatography (0-100% EtOAc in hexanes) to give the title compound.
