Reaction Steps

The benzyl (S)-6-(benzyloxycarbonylamino)-2-((2-methyl-1-(3-phenylpropanoylamino)propyl)(hydroxyphosphinoyl)oxy)hexanoate (85 mg) obtained in the above step (c) was dissolved in a mixed solvent of dioxane (2.4 ml) and water (0.8 ml) and added with palladium hydroxide (45.8 mg), and the mixture was stirred under a hydrogen atmosphere at room temperature for 24 hours. The reaction mixture was filtered with celite and the filtrate was concentrated. The residue was purified with HP-20 (Diaion, 10 cc, methanol:water=1:4 to 1:1) to obtain the title compound: (S)-6-amino-2-((2-methyl-1-(3-phenylpropanoylamino)propyl)(hydroxyphosphinoyl)oxy)hexanoic acid (25 mg, 45%) (a diastereoisomeric mixture of 1:1).
