실험 절차
0.27 g 0.64 mmol) of benzyl 2(RS)-[[(RS)-(ethoxy)[(2,5-dioxo-1-imidazolidinyl)methyl]phosphinyl]methyl]-4-methylvalerate was dissolved in 10 ml of ethanol and the solution was hydrogenated in the presence of 0.2 g of 10% palladium/carbon at room temperature and under atmospheric pressure. After 1 hours, the catalyst was removed by filtration and the solvent was evaporated to give 0.22 g of 2(RS)-[[(RS)-(ethoxy)[(2,5-dioxo-1-imidazolidinyl)-methyl]phosphinyl]methyl]-4-methylvaleric acid in the form of a foam;
