N-benzyloxycarbonyl-L-tryptophanyl-L-methionyl-L-aspartyl-DL-norvaline amide is dissolved in 10 parts glacial acetic acid containing 2 parts methylethyl sulfide. Then, 10 parts of 6 M hydrobromic acid in acetic acid is added and the solution is allowed to stand for one hour at room temperature. The solvents are removed under vacuum below 40° C. and the residue shaken with ether to afford L-tryptophanyl-L-methionyl-L-aspartyl-DL-norvaline amide hydrobromide. This compound is represented by the following formula.
