Abstract

The invention relates to a method for analyzing and measuring a Vildagliptin intermediate-5 enantiomer through high performance liquid chromatography. The method comprises the steps that a CHIRALPAK-AD-H type chiral chromatographic column is adopted, and after normal hexane-ethyl alcohol-methyl alcohol is adopted as a flow phase for chromatographic column separation, an ultraviolet detector is used for detecting the Vildagliptin intermediate-5 enantiomer. By means of the method, the enantiomer in Vildagliptin intermediate-5 can be effectively detected, and the quality of the Vildagliptin intermediate-5 can be better ensured. The method has the advantages of being high in specificity, high in accuracy and good in reproducibility.

Description

technical field [0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for analyzing and measuring vildagliptin intermediate-5 enantiomer by high performance liquid chromatography. Background technique [0002] Vildagliptin is a dipeptidyl peptidase Ⅳ inhibitor, which is a new oral drug for the treatment of diabetes. Vildagliptin intermediate-5 is one of the key intermediates in the synthesis of vildagliptin. Its chemical name is: S -1-(2-Chloroacetyl)pyrrolidine-2-carbonitrile. structural formula. [0003] Molecular formula: C 7 h 9 ClN 2 O; molecular weight: 172.61. [0004] In the process of synthesizing this compound, its enantiomers may affect the purity and quality of vildagliptin intermediate-5 due to incomplete removal. In the later stage of vildagliptin, there is no other refining means to reduce vildagliptin Therefore, the enantiomer of vildagliptin can only be controlled by controlling the content of en...
