Thiazolidinedione → HCID 86613944, compound

Participants

Reaction Steps

2.0 g of 1-benzyl-8-hydroxy-2-oxo-1,2,3,4-tetrahydroquinoline-5-carboxaldehyde and 0.874 g of 2,4-thiazolidinedione were suspended in 20 ml of toluene. Ten drops of piperidine and ten drops of acetic acid were added, followed by heating and refluxing for 8 hours. The resultant was allowed to cool to precipitate a solid, and the precipitated solid was collected by filtration and dried, giving 2.7 g (92% yield) of 5-(1-benzyl-8-hydroxy-2-oxo-1,2,3,4-tetrahydroquinolin-5-ylmethylidene)thiazolidine-2,4-dione as a yellow powder.
