Reaction Steps

By substituting N-[3-(3-fluoro-4-methoxybenzoyl)propionyl]-L-phenylalanine (prepared as described for the L-valine derivative of Example 21), m.p. 140°-146° C. for N-[3-(3-fluoro-4-methoxybenzoyl)propionyl-L-valine in the procedure of Example 21, one can obtain a glass which can be chromatographed over silica gel with hexane-ethyl acetate (4:1) containing 2% acetic acid to obtain N-[3-acetylthio-3-(3-fluoro-4-methoxybenzoyl)propionyl]-L-phenylalanine as a glass.
