Cool down to 50~55°C with tap water, filter with suction to remove insoluble matter, collect the filtrate, continue to cool down to 10~15°C to crystallize, filter to obtain a yellow solid. The yellow solid was dissolved with 80ml of absolute ethanol under reflux, cooled to 5-10°C, filtered, and the filter cake was dried under reduced pressure at 50-60°C for 5 hours. 10.0 g of the product was obtained with a yield of 60.0% and a purity of 96.2%. h 1 -NMR (600HZ, DMSO-d6): 7.86-7.87 (4H, m), 7.82-7.84 (4H, m), 7.08 (2H, d), 6.67 (2H, d), 6.67 (2H, d), 5.12 (2H, d), 4.14 (2H, s), 4.11 (2H, m), 3.93 (2H, t), 3.57-3.63 (8H,...

Abstract

The invention discloses a method for simultaneously detecting Rivaroxaban tablet relevant substances by high performance liquid chromatography. According to the chromatographic conditions, octadecyl silane is used as a filling agent of a chromatographic column; acetonitrile-buffer salts (containing phosphate and ion-pairing agents) are used as a flowing phase to perform gradient elution; an ultraviolet detector is used as a detector. By using the method provided by the invention, impurities in Rivaroxaban tablets can be effectively detected out; the analysis time is short; the efficiency is high; a simple and reliable method is provided for the Rivaroxaban tablets.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to a method for detecting related substances of rivaroxaban tablets. Background technique [0002] Rivaroxaban, Rivaroxaban, its chemical name is 5-chloro-N-({(5S)-2-oxo-3-[4-(3-oxomorpholin-4-yl)phenyl]-1, 3-oxazolin-5-yl}methyl)thiophene-2-carboxamide. [0003] The structural formula of rivaroxaban tablets is: [0004] [0005] The formulation of rivaroxaban is a highly selective, oral agent that directly inhibits factor Xa. Inhibition of factor Xa can interrupt the intrinsic and extrinsic pathways of the coagulation cascade, inhibit the generation of thrombin and thrombus formation, and have no direct effect on platelet aggregation. [0006] The synthetic process of rivaroxaban is as follows: [0007] [0008] Impurity No. chemical structure Impurities 1. Impurities 2. Impurities 3. Impurities 4. Impurities 5....
