When equivalent quantities of L-methionyl-L-aspartyl-DL-norvaline amide hydrochloride and N-benzyloxycarbonyl-L-tryptophan 2,4,5-trichlorophenyl ester are substituted for the L-methionyl-L-aspartyl-D-alanine amide hydrochloride and the N-t-butoxycarbonyl-L-tryptophan 2,4,5-trichlorophenyl ester of Example 6, and the procedure detailed therein substantially repeated, there is obtained N-benzyloxycarbonyl-L-tryptophanyl-L-methionyl-L-aspartyl-DL-norvaline amide. This compound is represented by the following formula.
