Procedure

To a solution of 0.896 g of methyl Boc-L-tyrosyl-D-norleucyl-glycyl-phenylalanyl-3-amino-1-adamantanecarboxylate in 10 ml of methyl acetate is added 10 ml of a 6 M solution of hydrogen chloride in dioxane. The reaction mixture is allowed to stand for one hour at room temperature, then the solvent is removed under vacuum. The residue is extracted with ethyl acetate. Removal of the solvent gives methyl L-tyrosyl-D-norleucyl-glycyl-L-phenylalanyl-3-amino-1-adamantanecarboxylate hydrochloride which is represented by the formula ##STR54##
