Abstract This study resolves conflicting data on a particular salt of the enantiomer of methyl α-5(4,5,6,7-tetrahydro(3,2- c )thieno pyridyl) (2-chlorophenyl)-acetate (S(+)clopidogrel). The title compound, (C 16 H 17 ClNO 2 S) + (C 3 H 7 O 4 S) − , was obtained and successfully characterized by X-ray diffraction, NMR, TG/DSC/MS. This salt previously reported in the literature as a 2-propanol solvate
摘要 本研究解决了关于 α-5(4,5,6,7-四氢 (3,2- c )噻吩并吡啶基) (2-氯苯基)-乙酸甲酯 (S(+)氯吡格雷)。获得标题化合物(C 16 H 17 ClNO 2 S) + (C 3 H 7 O 4 S) - 并通过X射线衍射、NMR、TG/DSC/MS成功表征。先前在文献中报道为硫酸氢盐的 2-丙醇溶剂化物的这种盐似乎实际上是异丙基硫酸盐。
