Abstract: Norfloxacin ethyl ester was prepared from 3-chloro-4-fluoroaniline in ionic liquid in a one-pot procedure by condensation with EMME [ethoxymethylenemalonic diethyl ester], cyclization, ethylation and condensation with anhydrous piperazine. After its hydrolysis, norfloxacin was obtained with an overall yield of 72.7%.
