Provided are a method for preparing (R)-3-(3-fluoro-4-(1-methyl-5,6-dihydro-1,2,4-triazin-4(1H)-yl)phenyl)-5-(substituted methyl)oxazolidin-2-one derivatives, which are oxazolidinone antibiotic compounds having a cyclic amidrazone group, represented by Chemical Formula 1, and intermediates thereof, and uses 3,4-difluoro-4-nitrobenzen as a starting material. According to the preparation method of the present invention, (R)-3-(3-fluoro-4-(1-methyl-5,6-dihydro-1,2,4-triazin-4(1H)-yl)phenyl)-5-(substituted methyl)oxazolidin-2-one derivatives, which are useful as oxazolidinone antibiotics, can be prepared in high purity and high yield in a simpler manner than conventional methods.
提供了一种制备(R)-3-(3-氟-4-(1-甲基-5,6-二氢-1,2,4-三嗪-4(1H)-基)苯基)-5-(取代甲基)噁唑烷酮衍生物的方法,这些衍生物是具有环氨基酮基团的噁唑烷酮抗生素化合物,由化学式1表示,以及它们的中间体,并使用3,4-二氟-4-硝基苯作为起始物质。根据本发明的制备方法,可以以比传统方法更简单的方式高纯度和高产率地制备用作噁唑烷酮抗生素的(R)-3-(3-氟-4-(1-甲基-5,6-二氢-1,2,4-三嗪-4(1H)-基)苯基)-5-(取代甲基)噁唑烷酮衍生物。
