実験手順

0.11 g (0.23 mmol) of (glutarimidomethyl)[(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid ethyl ester was dissolved in 4 ml of dicloromethane and the solution was stirred overnight in the presence of 2 ml of bromotrimethylsilane. The solvent was removed by evaporation and the residue was dissolved in 5 ml of acetone/water (9:1). The solvent was removed by evaporation and this treatment was repeated once more to give 0.1 g of (glutarimidomethyl)[(RS)-4-methyl-2-[[(S)-3-methyl-1-(methylcarbamoyl)butyl]carbamoyl]pentyl]phosphinic acid in the form of a foam.
