Procedure

To a solution of 6-bromo-5-trifluoromethyl-2-[4-(3-trifluoromethyl-pyridin-2-yl)-piperazin-1-yl]-1H-benzoimidazole (203 mg, 0.41 mmol, Example 89g) in dichloromethane (6 mL) was added N,N-diisopropylethylamine (148 mg, 1.15 mmol) followed by 2-(trimethylsilyl)ethoxymethyl chloride (94 mg,; 0.57 mmol, Aldrich). The reaction mixture was stirred at room temperature for 16 h. The solvent was removed in vacuo and the residue was purified by silica gel column chromatography, eluting with EtOAc/hexane (1:3) to afford the title compound as an amorphous solid. MS (ESI, pos. ion) m/z: 624 (M+1).
