실험 절차

A solution of methyl (2S,3R,5E)-3-({[(1S)-2,2-dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]amino}carbonyl)-2-ethoxy-6-(3-fluoro-4-phenoxyphenyl)hex-5-enoate (350 mg, 0.566 mmol) in ethanol (15 mL) was hydrogenated over 10% palladium on charcoal (60 mg) at 3 bar and 20° C. for 16 h. The mixture was filtered through Arbocel filter aid and concentrated under reduced pressure. The residue was dissolved in cyclohexane and evaporated (twice) to give methyl (2S,3R)-3-({[(1S)-2,2-dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]amino}carbonyl)-2-ethoxy-6-(3-fluoro-4-phenoxyphenyl)hexanoate (368 gm, 105%), as a colourless foam, which was taken onto the next step without purification.
