Synthesis and characterization of sitafloxacin

The convenient protocol for the synthesis of sitafloxacin is described. Reaction of ethyl 3-(3-choloro-2,4,5-trifluorophenyl)-3-oxopropanoate with triethylorthoformate and (1R,2S)-(-)-cis-1,2 fluorine cyclopropane amino-p-toluene sulfonic acid salt by condensation under sodium hydrogen condition. The reaction mixture take place hydrolysis of ester in hydrochloric acid solution. Subsequence reacted with (S)-N[(oxoboryl) methylene] -5-azaspiro[2,4]heptan-7-amine by condensation. In the end taken off the protection group gives sitafloxacin and total conversion about 52-65%. The structure of sitafloxacin was characterized by 1H NMR, 13C NMR, IR, MS and elemental analysis.
