実験手順

To 2-(S)-[2-(S)-allyloxycarbonylamino-3-(4-carbamimidoyl-phenyl)-propionylamino]-pentanedioic acid 5-tert-butyl ester 1-methyl ester hydrochloride (3.06 g, 5.8 mmol) in 100 ml of water and 30 ml of THF was added lithium hydroxide hydrate (0.49 g, 11.6 mmol). The solution was stirred at room temperature for 12 hours, evaporated, and freeze-dried. 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: 2.7 g (97%). MS: m/z=477.4 (M+H)+.
