Versuchsvorschrift
Under the conditions of Example 21(A), 5 g of 4-[N-benzyl-N-(2-carboxy-1-methylethyl)aminoacetyl]-7-benzyloxyindole-2-carboxylic acid hydrochloride is reacted with 1.6 g of chloromethylmethyl ether and worked up. Treatment of the crude product with dioxane/acetic acid yields 4.2 g of 4-[N-benzyl-N-(2-methoxymethoxycarbonyl-1-methylethyl)aminoacetyl]-7-benzyloxyindole-2-carboxylic acid methoxymethyl ester acetate, decomposition point 118°-122° C.
