Problems solved by technology

[0007] Due to the existence of this keto-enol tautomer, the prasugrel intermediate will appear double peaks in the liquid chromatogram, and it is difficult to separate. So far, USP, EP, BP, JP and Chinese Pharmacopoeia and The analysis and detection method of the prasugrel intermediate is not recorded in the patent literature, but the analysis and detection of the prasugrel intermediate plays an important role in the reaction control and yield improvement, and also directly affects the quality of the final product. A rapid and effective analytical detection method is very necessary for the quality control of prasugrel intermediates

Abstract

The invention relates to a method for analyzing and detecting a Prasugrel intermediate. The method is used for quality control of 5-[2-cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-5,6,7,7A-tetrahydrothieno[3,2-C]pyridine-2(4H)-one. The method realizes reversed phase high-performance liquid chromatography-based analysis and detection under the conditions of a chromatographic column (C18, 4.6*150mm, 5 microns) filled with octadecyl silane bonded silica gel which is used as a filling material, phosphoric acid aqueous solution-acetonitrile or acetic acid aqueous solution-acetonitrile as a mobile phase and detection wavelength of 220nm. The method has the advantages of high degree of separation, short analysis time, simple operation and stable and reliable analysis.

Description

technical field [0001] The invention relates to a high-performance liquid chromatography analysis method, in particular to an analysis and detection method of a prasugrel intermediate. Background technique [0002] Prasugrel is a tetrahydrothienopyridine drug jointly developed by Sankyo Company of Japan and Eli Lilly Company of the United States. It has a similar structure to clopidogrel, but is superior to clopidogrel in terms of activity, tolerance and safety. Clinical studies have shown that patients taking prasugrel have a lower comprehensive risk of heart attack and stroke, and the effect is quick after taking the drug, the blood concentration is stable, and the effect is long-lasting. [0003] 5-[2-Cyclopropyl-1-(2-fluorophenyl)-2-oxoethyl]-5,6,7,7A-tetrahydrothieno[3,2-C]pyridine-2( 4H)-ketone is an important intermediate for the synthesis of prasugrel, and its molecular formula is C 18 h 18 FNO 2 S, molecular weight 331.40, structural formula as follows: [0004...
