synthesized. These structures are confirmed by nuclear magnetic resonance spectroscopy and high‐resolution mass spectrometry. The impurities (S)‐2‐(2‐((4‐(5‐(aminomethyl)‐2‐oxooxazolidin‐3‐yl)phenyl)amino)ethoxy)acetohydrazide (A) and (S)‐4‐(4‐(((2‐oxooxazolidin‐5‐yl)methyl)amino)phenyl)morpholin‐3‐one (F) are confirmed and distinguished from their isomers by single‐crystal diffraction. This work proves
在利伐沙班的开发过程中,已鉴定并合成了七种与工艺有关的杂质。这些结构已通过核磁共振波谱法和高分辨率质谱法确认。杂质(S)-2-(2-(((4-(5-(氨基甲基)-2-氧代恶唑烷丁-3-基)苯基)氨基)乙氧基)乙酰肼(A)和(S)-4-(4- (((2-氧代恶唑啉丁-5-基)甲基)氨基)苯基)吗啉-3-酮(F)已通过单晶衍射确认并与它们的异构体区分开。在遵守监管规范和评估利伐沙班的质量方面,这项工作被证明是有价值的。
