실험 절차

To a solution of 4-formyl-(2′-chloro-1,1′-biphenyl) (0.12 g, 0.55 mmol) and 2,4-thiazolidinedione (0.08 g, 0.65 mmol) in toluene (10 mL) were added piperidine (0.008 mL, 0.073 mMol) and benzoic acid (0.011 mg, 0.08 mmol), and the reaction was refluxed for 4 h with continuous removal of water. The solvent was then distilled off and the oily residue obtained was purified by chromatography on silica-gel using hexane: ethyl acetate (3:1) as the eluent to yield titled product.
