Procedure

A mixture of 2 g (0.017 mol) thiazolidin-2,4-dione, 2 g (0.034 mol) acetic acid and 3 g (0.03 mol) piperidine were added to a solution of 5 g (0.017 mol) 4-[2-chloro-2-(5-ethyl-pyridin-2-yl)-ethoxy]-benzaldehyde dissolved in 50 mL toluene. Reaction mixture was heated and water was removed azeotropically. After completion of the reaction on TLC, toluene was distilled out completely under reduced pressure. Product was poured into excess of water and extracted with ethyl acetate. After concentrating ethyl acetate in vacuo and making its HCl salt in usual way 4.3 g (60%) desired product obtained.
