Versuchsvorschrift

N-4-Amidinobenzoyl-β-phenyl-α,α-dimethyl-β-alanyl-4-piperidineacetic acid benzyl ester (63 mg, 0.114 mmol) was dissolved in an 80% aqueous methanol solution (10 ml) containing 2% acetic acid. To the reulting solution was added palladium hydroxide (50 mg) and the mixture was stirred in a hydrogen atmosphere for 15 minutes. The solvents were distilled off and the res idue was dissolved in a 1N aqueous solution of acetic acid. The resulting solution was purified with a high performance liquid chromatography (HPLC) under the same conditions as described in (3) to yield a powder of N-(N-4-amidinobenzoyl-β-phenyl-α,α-dimethyl-β-alanyl-4-piperidineacetic acid (47.5 mg, 89.9%). The obtained product was identified by NMR, MS and HPLC analyses to be the same compound as prepared by the solid phase method.
