Procedure

To a stirred solution of 2,3-dichloro-4-methoxy-N-n-butylaniline (8.5 g) in 1,1,2,2-tetrachloroethane (80 ml) is added anhydrous aluminium chloride (8.5 g), and the mixture is refluxed for about 40 hours. The resulting mixture is poured into ice/water (about 500 ml), and the precipitated material is extracted twice with methylene chloride. The combined extracts are dried and evaporated in vacuo to give the title compound as a heavy oil.
