Disclosed is a process for producing a thiabenzoazulene-propionic acid derivative which is useful as an active ingredient of an antihistaminic agent or the like. According to the producing process of the present invention, it is possible to produce a thiabenzoazulene-propionic acid derivative where the 2-position of the thiabenzoazulene skeleton is substituted with propionic acid. The thiabenzoazulene propionic-acid derivative thus synthesized has excellent antagonistic action to histamine H1 receptor and low intracerebral transmigration and, therefore, is useful as an active ingredient of the pharmaceutical composition such as an antihistaminic agent.
本发明揭示了一种生产噻苯并噻唑蓝-丙酸衍生物的方法,该衍生物可用作抗组胺剂等药物的活性成分。根据本发明的生产方法,可以生产出噻苯并噻唑蓝-丙酸衍生物,其中噻苯并噻唑蓝骨架的2位被丙酸取代。因此,通过合成出的噻苯并噻唑蓝-丙酸衍生物具有优秀的对组胺H1受体的拮抗作用和低的颅内转移,因此可用作药物组合物的活性成分,例如抗组胺剂。
