Participants

Reaction Steps

To stirred solution of 5 g (0.015 mol) 4-[2-bromo-2-(5-ethyl-pyridin-2-yl)-ethoxy]-benzaldehyde dissolved in 50 ml, toluene was added 1.85 g (0.015 mol) thiazolidin-2,4-dione followed by addition of 2 g (0.03 mol) acetic acid and 3 g (0.03 mol) piperidine. 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. On concentrating ethyl acetate in vacuo, 0.65 g (10%) desired product obtained with satisfactory mass. The 1H NMR was similar to the 1H NMR of example 79.
