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.
本发明公开了一种制备一般式(I)的
噻吩[3,2-c]
吡啶衍生物的过程,可以是外消旋或光学活性(+)或(-)形式及其盐,其中苯环上的取代基X表示氢或卤素原子,例如
氟、
氯、
溴或
碘。本发明还描述了一种制备一般式(II)的化合物的过程,可以是外消旋或光学活性(+)或(-)形式及其盐,其中苯环上的取代基X表示氢或卤素原子,例如
氟、
氯、
溴或
碘。公式(I)和公式(II)所表示的化合物具有一个不对称碳,因此,公式(I)或公式(II)的光学活性化合物可以通过分离外消旋中间体/最终产物或使用光学活性中间体来获得。本发明的化合物具有药理活性,并具有显著的抗聚集和抗血栓性能。
