Reaction Steps

A mixture of 2-chloro-3-nitropyridine (1.15 g), 3-[(E)-2-(3-aminophenyl)vinyl]pyridine (1.23 g) and potassium carbonate (1.1 g) in 1,4-dioxane (15 ml) was stirred under reflux for 22 hours. After cooling, insoluble materials were removed by filtration and the filtrate was concentrated. The residue was chromatographed on silica gel column (2% methanol in chloroform) to give 3-nitro-2-[3-[(E)-2-(3-pyridyl)vinyl]phenylamino]pyridine (510 mg) as an orange solid.
