Versuchsvorschrift
N-[2-Acetylthiomethyl-5-(p-methoxybenzyloxycarbonylamino)pentanoyl]-L-tryptophane methyl ester (1 g) is dissolved in trifluoroacetic acid (10 ml), the solution is stored at room temperature for fifteen minutes, and then evaporated in vacuo to yield N-(2-acetylthiomethyl-5-aminopentanoyl)-L-tryptophane methyl ester, trifluoroacetate.
