実験手順

tert-Butyl (2S,3R,5E)-3-({[(1s)-2,2-dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]amino}carbonyl)-6-[3-methyl-(4-phenyl)phenyl]-2-(1-propyl)hex-5-enoate (437 gm, 0.68 mmol) in ethanol (50 mL) was hydrogenated over 10% palladium on charcoal (50 mg) at 3 bar and 20° C. for 17 h. The mixture was filtered through Arbocel filter aid and concentrated under reduced pressure. Flash chromatography (gradient elution with hexane:ethyl acetate) gave tert-butyl (2S,3R)-3-({[(1S)-2,2-dimethyl-1-({[(1R)-1-phenylethyl]amino}carbonyl)propyl]amino}carbonyl)-6-[3-methyl-(4-phenyl)phenyl]-2-(1-propyl)hexanoate (395 gm, 62%), as a colourless foam.
