Procedure

1.50 g of 1-(4-chlorobenzyl)-2-oxo-1,2-dihydroquinolin-4-carboxaldehyde and 0.826 g of 2,4-thiazolidinedione were suspended in 30 ml of toluene. Five drops of piperidine and five drops of acetic acid were added, followed by heating and refluxing for 6 hours. The resultant was allowed to cool to precipitate a solid, and the precipitated solid was collected by filtration and dried, giving 1.01 g (50% yield) of 5-[1-(4-chlorobenzyl)-2-oxo-1,2-dihydroquinolin-4-ylmethylidene]thiazolidine-2,4-dione as a light-brown powder.
