A novel process for preparing piperazinyl quinolone derivatives of the formula (I) is disclosed. The process comprises reacting dihaloquinolones with piperazine derivatives and tetraalkyl ammonium halides in the presence of a polar solvent such as acetonitrile, dimethylformamide, pyridine, sulfolane and dimethyl sulfoxide. ##STR1##
揭示了一种制备式(I)的哌嗪喹诺酮衍生物的新工艺。该工艺包括在极性溶剂(如乙腈、二甲基甲酰胺、吡啶、磺醚烷和二甲基亚砜)的存在下,将二卤喹诺酮与哌嗪衍生物和四烷基铵卤化物反应。
