Versuchsvorschrift
In a manner analogous to that described in Example 3(A), from 0.7 g of (aminomethyl)[(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid methyl ester acetate and 0.29 g of phenylmaleic anhydride, there was obtained 0.21 g of [(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl][(2-phenylmaleimido)methyl]phosphinic acid methyl ester in the form of a pale yellow foam.
