Versuchsvorschrift
Using a procedure similar to that described in Example 36, the product from Example AI ([S-(R*,R*)]-2-{2-amino-4-methyl-pentanoylamino}-3-(4-benzyloxy-phenyl)-propionic acid tert-butyl ester) (0.20 g, 0.45 mmol) and 4-isopropylphenylsulfonyl chloride (0.10 g, 0.45 mmol) were coupled to give the title compound as a white solid (0.20 g, 71%), mp=147-148° C.
