実験手順

1-Ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (EDCI) (0.096 mol) was added at room temperature to a mixture of 4-(4-aminophenyl)-1-piperazinecarboxylic acid ethyl ester (0.08 mol), 2-iodo benzoic acid (0.096 mol) and 1-hydroxybenzotriazole (HOBT) (0.096 mol) in DCM (500 ml). The mixture was stirred at room temperature overnight. Water was added. The mixture was extracted with DCM. The organic layer was separated, dried, filtered, and the solvent was evaporated. The residue was taken up in DIPE. The precipitate was filtered off and dried, yielding 39 g of 4-[4-[(2-iodobenzoyl)-amino]phenyl]-1-piperazinecarboxylic acid, ethyl ester (intermediate 27).
