Reaction Steps

5,5'-[2,5-furandiylbis(carbonylimino)]bis-1H-indole-2-carboxylic acid diethyl ester (60 mg, 0.11 mM) is suspended in methanol (0.4 mL) and treated with N NaOH (0.25 mL). After 5 days the reaction is evaporated in vacuo and the residue dissovlved in water and the solution acidified to pH 2 with N HCl. This solution is freeze dried leaving 5,5'-[2,5-furandiylbis(carbonylimino)]bis-1H-indole-2-carboxylic acid (22 mg).
