実験手順

When an equivalent quantity of N-t-butoxycarbonyl-L-tyrosylglycyl-α-aminoisobutyric acid or N-t-butoxycarbonyl-L-tyrosyl-α-aminoisobutyrylglycine is substituted for the N-t-butoxycarbonyl-L-tyrosylglycyl-L-alanine of Example 12, and the procedure detailed therein substantially repeated, there is obtained N-t-butoxycarbonyl-L-tyrosylglycyl-α-aminoisobutyryl-L-phenylalanyl-L-leucine benzyl ester or N-t-butoxycarbonyl-L-tyrosyl--α-aminoisobutyrylglycyl-L-phenylalanyl-L-leucine benzyl ester, respectively.
