Abstract:2,3,4,5-Tetrafluorobenzoyl chloride was used as the starting material to react with(E)-ethyl 3-(4-methylpiperazin-1-yl)acrylate. Then, this obtained intermediate reacted with N-methylformohydrazide to give a reaction mixture. In the end, this reaction mixture was hydrolized in akaline and a cyclization reaction was performed to give Mabrofloxacin. This novel method has the advantages of simple process, high yield, good quality, and little waste water emissions with high industrial value.
