Reaction Steps

A mixture of 2-(3-vinylphenylamino)-3-nitropyridine (12.9 g), 3-bromopyridine (12.7 g), palladium(II) acetate (0.24 g), copper(I) iodide (0.10 g), tri-o-tolylphosphine (0.65 g), triethylamine (25 ml) and acetonitrile (150 ml) was stirred under reflux under nitrogen overnight. After removal of the solvents, crude residue was chromatographed on silica gel (450 g, chloroform as eluent) to give 2-[3-[(E)-2-(3-pyridyl)vinyl]phenylamino]-3-nitropyridine as a reddish orange crystals (11.5 g).
