Versuchsvorschrift

3-(2-Bromo-5-trifluoromethyl-benzyl)-oxazolidin-2-one (0.234 g, 0.71 mmol), [4-methoxy-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid methyl ester (0.181 g, 0.59 mmol), and potassium carbonate (0.209 g, 1.48 mmol) were combined in DME (2.5 mL) and H2O (1.2 mL) and purged with N2 for 30 minutes. Tetrakis(triphenylphosphine)palladium (0) (0.069 g, 0.06 mmol) was added, and the reaction was stirred at 90° C. for 4 hours. After cooling to room temperature, the mixture was 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 (0-50% EtOAc in hexanes) to give the title compound.
