Reaction Steps

When an equivalent quantity of L-methionyl-L-aspartyl-D-alanine n-propylamide hydrochloride is substituted for the L-methionyl-L-aspartyl-D-alanine amide hydrochloride of Example 6, and the procedure detailed therein substantially repeated, there is obtained N-t-butoxycarbonyl-L-tryptophanyl-L-methionyl-L-aspartyl-D-alanine n-propylamide. This compound melts at about 143.5°-148° C. with decomposition and is represented by the following formula.
