The present invention relates to a new process for the preparation of (2Z,5Z)-5-(3-chloro-4- ((R)-2,3-dihydroxypropoxy)benzylidene)-2-(propylimino)-3-(o-tolyl)thiazolidin-4-one and to the new intermediate (R)-3-chloro-4-(2,3-dihydroxypropoxy)-benzaldehyde used in this process. (2Z,5Z)-5-(3-Chloro-4-((R)-2,3-dihydroxypropoxy)benzylidene)-2-(propylimino)-3- (o-tolyl)thiazolidin-4-one is described in WO 2005/054215 to act as an immunosuppressive agent. The present invention further also relates to a new process for the preparation of (R)-3-chloro-4-(2,3-dihydroxypropoxy)-benzaldehyde.
The invention relates to pharmaceutical compositions containing at least one thiazolidin-4-one derivative to prevent or treat disorders associated with an activated immune system. Furthermore, the invention relates to novel thiazolidin-4-one derivatives notably for use as pharmaceutically active compounds. Said compounds particularly act also as immunosuppressive agents.
