A general synthesis of 4-substituted 6-(2-imidazolinylamino)-5,8-dimethylquinolines 1 has been developed. All new compounds were synthesized from a common intermediate, 5,8-dimethyl-6-nitro-4-quinolone 3, the structure of which was confirmed by X-ray crystallography. This methodology involved the conversion of 3 into either a 4-chloro- or 4-bromoquinoline followed by the introduction of various 4-substituents
