Reaction Steps
The mixture of 2-[4-(3-bromo-pyridin-2-yloxy)-cyclohexyl]-1H-benzoimidazole (0.15 g, 0.40 mmol), 4-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-3,6-dihydro-2H-pyran (0.09, 0.40 mmol), Pd(dppf)Cl2, Na2CO3, dioxane and H2O was heated at 90° C. for 10 h under N2 atmosphere. Then the mixture was concentrated and the obtained residue was purified by silica gel chromatography (DCM:MeOH=10:1) to give 2-{4-[3-(3,6-dihydro-2H-pyran-4-yl)-pyridin-2-yloxy]-cyclohexyl}-1H-benzoimidazole (0.10 g, 0.267 mmol, 75% yield) as light yellow oil.
