실험 절차

A mixture of 2-(4-oxo-2-thioxo-thiazolidin-3-ylamino)-benzoic acid (0.078 g, 0.29 mmol), 5-(5-tert-butyl-2-hydroxy-phenyl)-furan-2-carbaldehyde and (0.075 g, 0.31 mmol) and ethylenediamine diacetate (0.056 g, 0.031 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), ether (2×1 mL) and hexanes (2 mL). The material was dried in a vacuum oven at 65° C. for 17 h to afford 2-{5-[1-[5-(5-tert-Butyl-2-hydroxy-phenyl)-furan-2-yl]-methylidene]-4-oxo-2-thioxo-thiazolidin-3-ylamino}-benzoic acid (135 mg, 94%) as a solid. 1H NMR (400 MHz, DMSO-d6): δ 1.37 (9H, s), 6.98 (1H, d, J=8.4 Hz), 7.23 (1H, d, J=3.6 Hz), 7.34 (1H, dd, J=8.8, 2.8 Hz), 7.39 (1H, d, J=3.6 Hz), 7.70 (2H, m), 7.74 (1H, s), 7.94 (1H, d, J=2.4 Hz), 8.01 (1H, m), 8.07 (1H, m). LC/MS. APCI 493.1, HPLC 100%.
