Abstract

During the process development of an anticoagulant drug, Rivaroxaban (1), three related substances were detected by a gradient high performance liquid chromatography (HPLC) method. Liquid chromatography mass spectrometry (LC-MS) was performed to identify the molecular mass of these impurities. A detailed study was undertaken to characterize these impurities. Based on the spectral data (1H NMR, 13C NMR and MS), these impurities were characterized as 2-[(2S)-2,3-dihydroxypropyl]-1H-indene-1,3(2H)-dione (impurity-1), [2-({4-[(5S)-5-({[(5-chloro-2-thienyl)carbonyl]amino}methyl)-2-oxo-1,3-oxazolidin -3-yl]phenyl}amino) ethoxy]acetic acid (impurity-2) and 5-chloro-N-[(2R)-2-hydroxy-3-{[4-(3-oxomorpholin-4-yl) phenyl]amino}propyl] thiophene-2-carboxamide (impurity-3). A practical and efficient approach for the synthesis of these impurities with good yields and purities by HPLC is described in this report. The structures of the synthesized impurities (imputiy-1, impurity-2 and impurity-3) were further confirmed by co-injecting these impurities with the standard Rivaroxaban sample containing all the three impurities. The retention times of synthesized impurities matches (co-eluted) with the retention times of the impurities present in the standard sample.
