A mixture of 3-vinylaniline (8 g), 2-chloro-3-nitropyridine (10.7 g) and potassium carbonate (18.6 g) in dioxane (80 ml) was stirred under reflux for 5 days. The reaction was extracted with chloroform, washed with water, dried over magnesium sulfate and evaporated. After evaporation of the solvent, crude residue was crystallized from methanol to give 2-(3-vinylphenylamino)-3-nitropyridine as an orange crystals (12.9 g).
