Abstract:The related substance (EP-A) produced from the degradation of Ticagrelor was obtained by four steps including condensation reaction, cyclization reaction, aminolysis and deprotection using 2-[[(3aR,4S,6R,6aS)-6-Amino-2,2-dimethyltetrahydro-3aH-cyclopentadieno-1,3-dioxolane-4-yl]oxy]-1-ethanol-L-tartrate and 2-propylthio-4,6-dichloro-5-aminopyrimidine as the starting materials. The yield was 66%, and the purity was 97.06%(HPLC). The EP-A was confirmed by LC-MS, 1H NMR. This substance was used as reference for quality control. |
