Reaction Steps

When equivalent quantities of N-t-butoxycarbonyl-L-tyrosylglycyl-α-aminoisobutyric acid and L-phenylalanyl-L-methionine benzyl ester are substituted for the N-t-butoxycarbonyl-L-tyrosylglycyl-L-alanine and L-phenylalanine-L-leucine benzyl ester, respectively, of Example 12, and the procedure detailed therein substantially repeated, there is obtained N-t-butoxycarbonyl-L-tyrosylglycyl-α-aminoisobutyryl-L-phenyl-alanyl-L-methionine benzyl ester.
