1-Substituted-6-fluoro-7-aryl-(8-fluoro)-1,4-dihydroquinol-4-one 3-carboxylic acids having antibacterial activity are prepared by reacting the corresponding alkyl 1-substituted-6-fluoro-7-bromo-(8-fluoro)-1,4-dihydroquinol-4-one-3-carbox ylate with an arylmetallic compound and hydrolyzing the ester formed.
具有抗菌活性的1-取代-6-氟-7-芳基-(8-氟)-1,4-二氢喹啉-4-酮3-羧酸是通过将相应的烷基1-取代-6-氟-7-溴-(8-氟)-1,4-二氢喹啉-4-酮-3-羧酸酯与芳基金属化合物反应,并水解形成的酯来制备的。
