Procedure

A mixture of 4-bromo-2-[(2R)-4-(3,5-dichloro-pyridin-2-yl)-2-methyl-piperazin-1-yl]-6-trifluoromethyl-1H-benzoimidazole (204 mg, 0.4 mmol, Example 149b), 4-trifluoromethylphenylboronic acid (152 mg, 0.8 mmol, Aldrich), Pd(PPh3)4 (46 mg, 0.04 mmol, Aldrich) and Na2CO3 (2 mL, 0.8 mmol, 0.4 M in H2O) in MeCN (4 mL) was heated at 90° C. with stirring for 16 h. Water (10 mL) was added and the mixture was extracted with EtOAc (2×30 mL). The combined organic extracts were washed with brine (5 mL), dried over Na2SO4 and filtered. The filtrate was evaporated in vacuo and the residue was purified by silica gel column chromatography, eluting with 10% EtOAc/hexane to give the title compound. MS (ESI, pos. ion) m/z: 574 (M+1).
