Versuchsvorschrift
A solution of Boc-Gly-Gly-Ala-Gly-OMe (2.0 g, 5.35 mmole, described in Example 4) in trifluoroacetic acid (25 ml) is stirred at 0° C for 1 hr. The solvent is evaporated, the residue triturated with ether, the solid collected and dried to give the tetrapeptide of formula H-Gly-Gly-Ala-Gly-OMe isolated as the trifluoroacetic acid addition salt.
