Reaction Steps
1.27 g of 5-bromo-3-nitro-1-phenyl-1,2-dihydropyridin-2-one, 2.38 g of 2-tri-n-butyl stannyl pyridine and 248 mg of tetrakistriphenylphosphine palladium were added to 20 ml of xylene, followed by stirring at 120° C. overnight in nitrogen atmosphere. The reaction mixture was purified by silica gel chromatography (ethyl acetate/hexane system), to give 638 mg of the title compound.
