Reaction Steps

To a solution of 655 mg (1.52 mmol) [2-(4-isopropyl-phenyl)-7-methoxy-1-(2-methoxy-ethyl)-4-trifluoromethyl-1H-benzoimidazol-5-yl]-methanol in 10 ml THF, 604 mg (2.28 mmol) triphenylphosphine and 764 mg (2.28 mmol) carbon tetrabromide are added at 0° C. The mixture is stirred at 0° C. for 10 min and 30 min at room temperature. Then the reaction mixture is poured on water and extracted (3×) with ethyl acetate. The combined organic layers are washed with water (2×) and brine, dried over MgSO4, filtered and concentrated in vacuo. The residue is purified by flash-chromatography on silica gel (hexane:EtOAc=2:1−>1:1) to afford 660 mg of the title compound as a colorless crystalline solid.
