Abstract

Novel 1-R-1,4-dihydro-4-oxo-6-fluoro-7-(Z.dbd.N--)-quinolinecarboxylic acids and esters thereof, where R is amino, lower-alkylamino, 2-propenylamino or di-lower-alkylamino, R" is hydrogen or lower-alkyl, and Z.dbd.N is a heterocyclic group, useful as antibacterial agents, are prepared by reacting the corresponding 7-chloroquinoline derivatives with the appropriate heterocyclic compound, Z.dbd.NH. A preferred group of compounds are those where Z.dbd.N is 1-piperazinyl or 4-lower-alkyl-1-piperazinyl.
