1 mol of 2,6-dichloro-3-nitrotoluene in 1 l of dimethyl sulfoxide was stirred at 150° for 5 hours with 1 mol of copper (I) cyanide. The mixture was then cooled, poured into water and extracted with ethyl acetate. The organic phase was evaporated and the residue was purified by chromatography on silica gel. There was obtained 2-methyl-3-chloro-6-nitrobenzonitrile (yield 60%), m.p. 97°-98°.
