Procedure

5-(3-Iodophenyl)furan-2-carbaldehyde (30 mg, 0.1 mmol) and ethyl-2-(4-oxo-2-thioxothiazolidin-3-yl)acetate (22 mg, 0.1 mmol) were dissolved in dichloromethane (7 mL), piperidine (20 μL) was added thereto, and the mixture was stirred at room temperature (25° C.) for 3 hours. After the reaction was completed the solvent was removed by evaporation under reduced pressure, and the residue was subjected to silica gel column chromatography using ethyl acetate/hexane (3/7 (volume ratio)) as an eluent, to give the target compound 1 in a yield of 38 mg (yield 76.2%).
