The invention discloses a method for preparing quinolone medicaments. The conventional methods using organic solvents with a high boiling pint and a large polarity, adopting other solid alkali materials except reaction materials or using other liquid alkali materials except the reaction materials have obvious defects. The method of the invention adopts a technical scheme that: quinolone compounds are prepared by a piperazidine reduction of quinolone carboxylate nuclear parent and piperazidine derivates in water; the piperazidine reduction is completed in the presence of a catalyst which may be one or a mixture of more than two of cerous chloride heptahydrate, N,N-carbonyldiimidazole, 4-dimethylamino pyridine, tetrabutylammonium bromide, benzyl triethylammonium chloride and tetrabutyl ammonium hydroxide. The method for preparing the quinolone medicaments radically solves the problems of terrible smell, realizes clean production, avoids using the other alkali substances except the reaction ...

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 ...
