Reaction Steps
A mixture of 5-amino-1-cyclopropyl-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylic acid, 1-ethylpiperazine, and acetonitrile was refluxed for 5 hours. After cooling, the resulting crystals were filtered, washed with water and recrystallized from ethanol to give 5-amino-1-cyclopropyl-6,8-difluoro-7-(4-ethyl-1-piperazinyl)-1,4-dihydro-4-oxoquinoline-3-carboxylic acid, m.p. 236°-237° C.
