실험 절차

1.7 ml (1.70 mmol) of an aqueous 1M lithium hydroxide solution are added to a solution containing 620 mg (1.13 mmol) of methyl (S)-3-{3′-[(benzoylmethylamino)methyl]biphenyl-4-yl}-2-(1-methyl-3-oxo-3-phenyl-propenylamino)propionate in 10 ml of a methanol/THF mixture (3/1). After stirring for 16 h, the medium is acidified with 1N hydrochloric acid until pH=4, extracted with ethyl acetate, dried over magnesium sulfate, and concentrated. The residue is purified by chromatography on a column of silica and eluted with a heptane/ethyl acetate mixture. 100 mg of (S)-3-{3′-[(benzoylmethylamino)methyl]biphenyl-4-yl}-2-(1-methyl-3-oxo-3-phenylpropenylamino)propionic acid are isolated with a 17% yield.
