実験手順

A mixture of 2-(4-oxo-2-thioxo-thiazolidin-3-ylamino)-benzoic acid (0.092 g, 0.34 mmol), 5-(3-nitrophenyl)furan-2-carbaldehyde (0.071 g, 0.33 mmol) (purchased from Aldrich Chemical Company) and ethylenediamine diacetate (0.059 g, 0.033 mmol) in methanol (10 mL) was stirred at room temperature for 18 h. The reaction mixture was poured into stirred 0.6 N aq sodium hydrogensulfite (50 mL). The mixture was vigorously stirred for 30 min. The solid product was filtered off and washed on funnel successively with 0.6 N aq sodium hydrogensulfite (1 mL), water (2×2 mL), acetonitrile (1 mL), ether (2×2 mL) and acetonitrile (1 mL). The material was dried in a vacuum oven at 65° C. for 17 h to afford 2-{5-[1-[5-(3-Nitro-phenyl)-furan-2-yl]-methylidene]-4-oxo-2-thioxo-thiazolidin-3-ylamino}-benzoic acid (115 mg, 72%) as a solid. 1H NMR (400 MHz, DMSO-d6): δ 6.62 (1H, m), 6.90 (1H, m), 7.37 (1H, m), 7.44 (1H, d, J=3.6 Hz), 7.64 (1H, d, J=3.6 Hz), 7.80 (1H, s), 7.88 (1H, m), 7.92 (1H, m), 8.28 (2H, m), 8.65 (1H, m), 10.2 (1H, bs). LC/MS: APCI 466.7, HPLC 96.5%
