A new procedure for making 2,3-quinolinedicarboxylic acid (6), starting with aniline and maleic anhydride has been developed.Evidence for the formation of 2-anilino-3-formyl-N-phenylmaleimide (7) in the cyclization of 3-phenylimino-4-dimethylaminomethylene-N-phenylsuccinimide (4a) to N-phenylacridinimide (5a) is presented.
