Under a nitrogen atmosphere, to a mixture of 6-bromo-2-methoxy-3-(4-methyl-1H-imidazol-1-yl)pyridine (25 g) and zinc cyanide (16.4 g) in DMF (250 mL) was added tetrakis(triphenylphosphine)palladium(0) (2.16 g) at room temperature, and the mixture was stirred at 120° C. for 2 hr. The reaction mixture was allowed to cool to room temperature, and diluted with ethyl acetate and 10% aqueous ammonia solution. The precipitate was collected by filtration, washed with ethyl acetate and dried to give the title compound (17.5 g)
