Application
2-Chloro-3-nitrobenzoic acid was used as reagent during the synthesis of new biprivileged molecular scaffolds of tetracyclic indolo-benzodiazepines and indolo-quinoxalines. It was used in a microwave-promoted Ulmann condensation with 2-aminopyridines.
General description
2-Chloro-3-nitrobenzoic acid undergoes condensation with aminoquinolines to yield phenylquinolylamines.

The present article describes the design and synthesis of new biprivileged molecular scaffolds with diverse structural features. Commercially available, simple heterocyclic building blocks such as 4-fluoro-3-nitrobenzoic acid, 2-chloro-3-nitrobenzoic acid, and indoline were utilized for the synthesis of the novel heterocycles.

Condensation of either 2-bromobenzoic acid (4) or 2-chloro-3-nitrobenzoic acid (5) with suitable aminoquinolines 6-8 afforded phenylquinolylamines 9-13. Acid mediated cyclization gave the corresponding 12H-benzo[b][1,7]phenanthrolin-7-ones 14 and 15, and 12H-benzo[b][1,10]phenanthrolin-7-ones 16-18. Compounds 14, 16, and 17 were subsequently N-methylated to 6-demethoxyacronycine
