Procedure

To a solution of 3-formyl-(2′-trifluoromethoxy-1,1′-biphenyl) (0.31 g, 1.16 mmol) and 2,4-thiazolidinedione (0.164 g, 1.4 mmol) in toluene (20 mL) were added piperidine (0.015 mL, 0.152 mmol) and benzoic acid (0.021 mg, 0.175 mmol), and the reaction was refluxed for 3 h with continuous removal of water. The solvent was then distilled off and the residue was crystallized from ether-pet ether to yield titled product as a solid.
