Versuchsvorschrift

To 2-(S)-[2-(S)-allyloxycarbonylamino-3-(4-carbamimidoyl-phenyl)-propionylamino]-pentanedioic acid 5-tert-butyl ester (48 mg, 0.1 mmol) and 2-(S)-amino-N1-phenylethyl-succinamide hydrochloride (27 mg, 0.1 mmol) in 5 ml of DMF were added at 0° C. HATU (39 mg, 0.1 mmol) and collidine (24.2 mg, 0.2 mmol). The mixture was stirred for 1 hour and then allowed to warm to room temperature. After evaporation the residue was purified by chromatography on Sephadex LH20 employing n-butanol/glacial acetic acid/water (17/1/2) as eluent. Pure fractions were combined. The solvent was evaporated, the residue was taken up in water and the aqueous solution was freeze-dried. Yield: 45 mg (66%). MS: m/z=638.4 (M+H)+.
