Reaction Steps

To a mixture of copper iodide (0.16 g, 0.85 mmol) and 1,10-phenanthroline (0.31 g, 1.7 mmol) in anhydrous DMF (4.2 mL) was added benzimidazole (1.00 g, 8.5 mmol), 1-bromo-4-iodobenzene (2.88 g, 10.1 mmol), and cesium carbonate (5.53 g, 17 mmol) and the reaction mixture was heated to 110° C. and allowed to stir for 40 h. The reaction mixture was cooled to room temperature and the solvent was evaporated under reduced pressure. The residue was partitioned between water and dichloromethane and the organic layer was separated, dried (Na2SO4) and the solvent removed under reduced pressure. Purification by flash column chromatography (silica, petroleum ether:ethyl acetate 1:1) provided the title compound (64%). LCMS (ESI+) 274.2 (MH+).
