Preparation method of ciprofloxacin hydrochloride

The invention discloses a preparation method of ciprofloxacin hydrochloride. The existing synthesis method generally uses isoamyl alcohol and the like as solvent, thus having the problems of strong smell, difficult biodegradation and higher environmental pollution. If the solvent such as the isoamyl alcohol and the like is used, more alkali insoluble substances and acidic insoluble substances are generated in recovery after the reaction, so that the insoluble substances are needed to be treated by purification through the steps such as alkali-dissolving heat-filtering call-back throw filter, acidic-dissolving heat-filtering call-back throw filter, salifying decoloration heat-filtering and the like, the process route is longer, and the product yield is lower. The preparation method of the ciprofloxacin hydrochloride selects the proper solvent as reaction medium, firstly leads cyclopropane carboxylic acid and piperazine to have piperazine reduction reaction and then leads the reaction product to be salified together with hydrochloric acid. In the reaction process, less alkali insoluble substances and acidic insoluble substances are generated in the reaction process, and the ciprofloxacin hydrochloride can be obtained by salifying decoloration heat-filtering, separation by crystallization, throw filter, rinsing and drying after being directly cooled and leached, so that the time for occupying equipment and the time of working procedures are shortened, and the production efficiency of a workshop is improved.
