Reaction Steps

The mixture of 4-(1H-benzoimidazol-2-yl)-cyclohexanol (0.36 g, 1.67 mmol), 3-bromo-2-chloro-pyridine (0.64 g, 3.34 mmol), t-BuONa (0.37 g, 3.34 mmol) and DMSO (5 mL) was heated at 60° C. for 2 days under N2 atmosphere. Then the mixture was concentrated under vacuum and the obtained residue was purified by silica gel chromatograph (DCM:MeOH=10:1) to give 2-[4-(3-bromo-pyridin-2-yloxy)-cyclohexyl]-1H-benzoimidazole (0.15 g, 0.403 mmol, 36% yield) as white solid.
