Abstract
The invention relates to a process for preparing substituted naphthyridine carboxylic acid derivatives of the formula I, <IMAGE> in which Z is the group<IMAGE> in which R2 is hydrogen or lower alkyl, the group<IMAGE> in which Y is O or S, or the group<IMAGE> in which n' is 4-5 and R3 is hydrogen or hydroxyl; and R1 is hydrogen or lower alkyl, and their pharmaceutically acceptable acid addition salts and base salts. These compounds possess antibacterial properties. The invention also relates to novel intermediates which can be used for preparing the compounds of the formula I.
