Abstract

The invention relates to an analysis method for determining stereoisomers and intermediates in solifenacin succinate by adopting high-performance liquid chromatography. The analysis method is characterized in that high-performance liquid chromatography (HPLC) is adopted, and isocratic elution is carried out on an amylose-tris(3,5-dimethylphenyl carbamate) bonded silica gel chiral HPLC column; a mobile phase is n-hexane-absolute ethyl alcohol-isopropyl alcohol-diethylamine solution (65:15:20:0.1) (volume ratio); and the mobile phase is adopted to dissolve a sample. The method can be used for simultaneously determining enantiomers and a diastereoisomer of the solifenacin succinate and intermediates as mutual enantiomers, thus providing a more reliable guarantee for the research on new synthesis process routes for the solifenacin succinate and quality control.

Description

Technical field [0001] The invention relates to an analytical method for the determination of stereoisomers and intermediates in soline succinate, in particular to the enantiomers and diastereomers of soline succinate by high performance liquid chromatography A method for separation and quantitative determination of a conformer and two intermediates that are enantiomers of each other. Background technique [0002] The chemical name of Solinasine succinate is (3R)-1-azabicyclo[2,2,2]octan-3-yl(1S)-1-phenyl-3,4-dihydroisoquinoline- 2-(1H)-formate succinate is a highly selective bladder M receptor antagonist, and its main structure is Solinasine. [0003] [0004] There are two chiral centers in the new structure of Solina succinate and three optical isomers; the intermediate structure contains one chiral center and two optical isomers. According to the requirements of "Technical Guidelines for Impurity Research of Chemical Drugs", stereoisomers should be controlled as impurities in...
