    • The present invention discloses a process for the preparation of thieno[3,2-c]pyridine derivatives of general formula (I), in either racemic or optically active (+) or (-) forms and their salts, wherein X, the substituent on benzene ring represents either a hydrogen or halogen atom such as fluorine, chlorine, bromine or iodine. The present invention also describes a process for preparing the compounds of general formula (II), in either racemic or optically active (+) or (-) forms and their salts, where X, the substituent on benzene ring represents either a hydrogen or halogen atom such as fluorine, chlorine, bromine or iodine. The compounds represented by formulae (I) and (II) have one asymmetric carbon and hence, the optically active compounds of formula (I) or of formula (ii), may be obtained either by resolving the racemic intermediate/final product or using an optically active intermediate. The compounds of the invention are pharmacologically active and have significant anti-aggregating and anti-thrombotic properties.
    • 本发明公开了以外消旋或光学活性(+)或( - )形式制备通式(I)的噻吩并[3,2-c]吡啶衍生物及其盐的方法,其中X为取代基 苯环表示氢或卤素原子,例如氟,氯,溴或碘。 本发明还描述了以外消旋或光学活性(+)或( - )形式制备通式(II)化合物及其盐的方法,其中X,苯环上的取代基表示氢或卤素 原子如氟,氯,溴或碘。 由式(I)和(II)表示的化合物具有一个不对称碳,因此式(I)或式(ii)的光学活性化合物可以通过拆分外消旋中间体/最终产物或使用 光学活性中间体。 本发明的化合物具有药理活性并且具有显着的抗聚集和抗血栓形成性质。
