実験手順

3-(4-oxo-2-thioxo-thiazolidin-3-yl)-cyclohexanecarboxylic acid (80 mg, 0.31 mmol), 5-(4-cyclohexyl-phenyl)-furan-2-carbaldehyde (84 mg, 0.33 mmol), and diethylenediamine diacetate (59 mg, 0.33 mmol) were combined in a 20 mL vial with ethanol (5 mL) and stirred at room temperature for 65 h. The reaction mixture was diluted with 10% methanol in dichloromethane (200 mL) and aqueous ammonium chloride (20 mL) and stirred at room temperature for 15 minutes. The layers were separated and the aqueous layer was extracted with 10% methanol in dichloromethane (2×100 mL). The combined organic extracts were washed with 0.6 N sodium hydrogensulfite (1×20 mL) and then brine (1×20 mL), dried (sodium sulfate) and concentrated under vacuum. The residue was triturated with dichloromethane/hexanes (1:5, 30 mL), filtered and dried overnight in a vacuum oven at 55° C. to afford 3-{5-[1-[5-(4-cyclohexyl-phenyl)-furan-2-yl]-methylidene]-4-oxo-2-thioxo-thiazolidin-3-yl}-cyclohexanecarboxylic acid (100 mg, 65%) as a solid. 1H NMR (400 MHz, DMSO-d6): δ 1.25-1.49 (7H, m), 1.67-1.92 (10H, m), 2.35-2.45 (2H, m), 2.56 (1H, m), 4.97 (1H, m), 7.26 (1H, d, J=3.6 Hz), 7.36 (1H, d, J=3.6 Hz), 7.42 (1H, d, J=8.4 Hz), 7.59 (1H, s), 7.77 (1H, d, J=8.4 Hz), 12.18 (1H, s); APCI-MS: 495.37; HPLC: 90%.
