Synthesis of 2,3-Quinolinedicarboxylic Acid
Maulding, Donald R.
, p. 1777 - 1779 (2007/10/02)
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.
