The present invention describes a novel process for the preparation of marbof loxacin and intermediate thereof comprising reaction of ammonium hydroxide of formula (III), NR1R2R3R4, wherein R1, R2, R3 and R4 are independently selected from the group of H, alkyl, alkylaryl, aryl and/or heteroaryl, with compound of formula (II), wherein R is selected from H, alkyl, arylalkyl, alkali metal cation,, NH4 cation, NR1R2R3R4cation; X is halogen, such as chloro, bromo, fluoro, piperazinyl, which may be substituted or unsubstituted, and R' is selected from H, formyl or COOAlkyl.
该发明描述了一种新颖的马伯氟沙星及其中间体的制备方法,包括将化学式(III)的氢氧化铵(NR1R2R3R4,其中R1、R2、R3和R4独立地选自H、烷基、烷基芳基、芳基和/或杂环烷基)与化学式(II)的化合物反应,其中R选自H、烷基、芳基烷基、碱金属阳离子、NH4阳离子、NR1R2R3R4阳离子;X为卤素,如氯、溴、氟、哌嗪基,可能被取代或未取代,R'选自H、甲酰基或COO烷基。
