Reaction Steps

When equivalent quantities of N-t-butoxycarbonyl-DL-tyrosylglycyl-DL-alanine and DL-phenylalanyl-DL-leucine benzyl ester are substituted for the N-t-butoxycarbonyl-L-tyrosylglycyl-L-alanine and L-phenylalanyl-L-leucine benzyl ester, respectively in Example 12 and the procedure detailed therein substantially repeated, there is obtained N-t-butoxycarbonyl-DL-tyrosylglycyl-DL-alanyl-DL-phenylalanyl-DL-leucine benzyl ester.
