Abstract: | A one-pot synthesis of ethyl 8,9-difluoro-6-oxo-6H-benzoc]quinolizine-5-carboxylate 11 has been developed. The condensation of ethyl 2-pyridylacetate and 2,4,5-trifluorobenzoyl chloride followed by intramolecular nucleophilic aromatic substitution gave the desired ring system. This intermediate was converted to the title compound and its in vitro biological activity is reported. |
