Procedure
A solution of 1-bromo-2-fluoro-4-trifluoromethyl-benzene (5.0 g, 20.6 mmol) and DIEA (7.2 mL, 41.1 mmol) in toluene (100 mL) is degased under N2 atmosphere. To this mixture, Pd2 dba3 (753 mg, 0.82 mmol), Xantphos (952 mg, 1.65 mmol) and 3-mercapto-propionic acid 2-ethyl-hexyl ester (5.9 mL, 25.7 mmol) are added and the reaction is heated at reflux overnight. The resulting mixture is filtered over a plug of silica (EtOAc) and the organic is concentrated in vacuo. Purification by silica chromatography (EtOAc/petroleum ether; 3:97) affords the desired product.
