実験手順

In a manner analogous to that described in Example 24(A), from 0.17 g (1.09 mmol) of 2(S)-isobutylsuccinic anhydride and 0.32 g (0.73 mmol) of (aminomethyl)[(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid ethyl ester acetate, there was obtained 0.16 g of [[(S)-2-isobutylsuccinimido]methyl][(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid ethyl ester.
