Participants

Reaction Steps

5,5'-[1H-pyrrole-2,5-diylbis(carbonylimino)-bis-1H-indole-2-carboxylic acid diethyl ester (42 mg, 08 mM) is dissolved in pyridine (1 mL) and the solution treated with N NaOH (0.2 mL). After 24 hrs the reation is treated with additional N NaOH (0.4 mL). After an additional 96 hrs the reaction is evaporated in vacuo and the residue dissolved in water (5 mL). The aqueous solution is acidified with N HCl to pH 2 and then freeze-dried, leaving 5,5'-[1H-pyrrole-2,5-diylbis(carbonylimino)-bis-1H-indole-2-carboxylic acid.
