Versuchsvorschrift

In a manner analogous to that described in Example 3(A), from 0.52 g of (aminomethyl)[(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid ethyl ester acetate and 0.34 g of diphenylmaleic anhydride, there was obtained 0.581 g of [(2,3-diphenylmaleimido)methyl][(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid ethyl ester in the form of a yellow-green foam.
