실험 절차

A solution of (S)-3-[[ethoxy(6-phthalimidohexyl)phosphinyl]amino]-2-oxo-1-piperidineacetic acid, ethyl ester in dioxane is treated with hydrazine hydrate and stirred at room temperature under argon. After the reaction is completed, the mixture is diluted with toluene and the solvents decanted. The residue is triturated with methylene chloride and filtered. The combined filtrate is evaporated to dryness to give (S)-3-[[(6-aminohexyl)ethoxyphosphinyl]amino]-2-oxo-1-piperidineacetic acid, ethyl ester.
