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.
