  • Patent number: 5066800
    Abstract: A novel process and intermediates used therein for linking a cephalosporin compound to a quinolone are disclosed. According to the disclosed process, the 2-carboxylic acid moiety of the cephalosporin compound is treated with an organic base. The resulting salt is then reacted with a quinolone compound which has been activated using a haloformate. The reaction is run in a non-aqueous organic solvent. 4-Dimethylaminopyridine is used to promote the reaction between the cephalosporin salt and the activated quinolone.
