Reaction Steps

A mixture of 1-phenyl-2-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)-1H-benzo[d]imidazole (3 mmol), 2-bromo-5-iodopyridine (1.98 g, 7 mmol) (Compound 10), Pd(PPh3)4 (0.346 g, 0.3 mmol) and potassium carbonate (0.828 g, 6 mmol) in dioxane/water (50 mL/10 mL) was degassed and heated at about 80° C. overnight. The mixture was poured into ethyl acetate (250 mL), washed with water, then brine, dried over Na2SO4, loaded on silica gel and purified by flash column (hexanes/dichloromethane 1:1 to dichloromethane to dichloromethane/ethyl acetate 9:1 to 4:1). The desired fraction was collected and concentrated, then filtered to give a light yellow solid (Compound 11) (0.78 g, in 61% yield).
