Procedure

A mixture of 11.21 g (70 mmol) of 2-chloro-3-nitropyridine and 19.56 g (210 mmol) of aniline was heated under stirring at 100° C. for 1 h. The reaction liquid was cooled to room temperature and dissolved in ethyl acetate. The solution was washed with an aqueous citric acid solution and then with water. After drying over magnesium sulfate, the solvent was distilled off under reduced pressure and the residue was recrystallized from ethyl acetate/n-hexane to obtain 13.7 g of the title compound.
