Reaction Steps

When equivalent quantities of N-t-butoxycarbonyl-D-tyrosylglycyl-D-alanine and D-phenylalanyl-D-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-D-tyrosylglycyl-D-alanyl-D-phenylalanyl-D-leucine benzyl ester.
