Abstract

The invention provides a liquid chromatography analysis method for a chiral intermediate of ticagrelor, wherein the chiral intermediate is 2-[[(3aR, 4S, 6R, 6aS)-6-aminotetrahydro-2 , 2-dimethyl-4H-cyclopentene-1,3-dioxolane-4-yl] oxy]ethanol, comprising the following steps: precision measuring ticagrelor chiral intermediate solution respectively , sodium bicarbonate aqueous solution, derivative reagent solution, vortex mixing, react for a certain period of time, then add hydrogen chloride aqueous solution, vortex mixing, and obtain the ticagrelor chiral intermediate derivative solution; the ticagrelor The chiral intermediate derivative solution was subjected to chromatographic analysis. The liquid chromatography analysis method of the invention can accurately and sensitively detect the content of the chiral intermediate and its enantiomer.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a liquid chromatography analysis method for a chiral intermediate of ticagrelor. Background technique [0002] 2-[[(3aR,4S,6R,6aS)-6-aminotetrahydro-2,2-dimethyl-4H-cyclopentene-1,3-dioxolan-4-yl]oxy Base] ethanol is an important chiral intermediate in the synthesis of ticagrelor, and its enantiomer 2-[[(3aS,4R,6S,6aR)-6-aminotetrahydro-2,2-di Methyl-4H-cyclopentene-1,3-dioxolan-4-yl]oxyl]ethanol usually exists in the commercially available ticagrelor chiral intermediate products, and the structural formulas of the two are respectively as follows: [0003] [0004] The ultraviolet absorption of the above-mentioned ticagrelor chiral intermediate and its enantiomers is relatively weak, and the conventional high-performance liquid chromatography (HPLC) with an ultraviolet detector cannot detect this chiral intermediate and its opposite sensitively. The content of enantiomers has the pr...
