氟哌酸制备

邻二氯苯经硝化，或对硝基氯苯经氯化均可得3，4-二氯硝基苯。再在二甲亚砜中，和氟化钾回流，氟化得3-氯-4-氟硝基苯。在盐酸或乙酸水溶液存在下，用铁粉还原成3-氯-4-氟苯胺。接着和原甲酸三乙酯及丙二酸二乙酯(生成乙氧基亚甲基丙二酸二乙酯)在硝酸铵存在下回流，得缩合产物。在液体石蜡或二苯醚中加热环合，生成7-氯-6-氟-4-羟基喹啉-3-羧酸乙酯。进行乙基化后，再水解得乙基化产物。最后与哌嗪缩合得诺氟沙星。其工艺比较成熟，收率较高，一般能达到40%～65%，但7位引入哌嗪基时，6位氟原子被取代的副产物可占25%，分离困难，影响收率。以对硝基氯苯计总收率为8%以上。

在引入吡嗪环前，1-乙基-6-氟-7-氯-1，4-二氢-4-氧代喹啉-8-羧酸乙酯先和氟硼酸或三氟化硼-乙醚或乙酸硼反应，使4位上的羰基形成硼螯合物，然后再引入吡嗪基，可使7位氟被置换的副反应减少，收率可提高15%以上，且产品的质量改善。

诺氟沙星的合成，国内外研究较多，但真正用于工业生产的却不多。其合成路线的改进主要体现在两个方面。一是对成环工艺进行改进，二是在哌嗪基的引入上做些文章。
