4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids with a range of substituents on the pyridine ring is described. Starting with the appropriately substituted aniline and using the first two steps of the Gould-Jacobs quinoline synthesis the 7-pyridinyl-3-quinolinecarboxylates can be obtained. Ethylation at the 1-position and hydrolysis of the ester group gives the desired acid products. These compounds have significant
