Procedure
A mixture of (4-{(R)-2-[(E)-4-(3-chlorophenyl)-3-oxo-but-1-enyl]-5-oxo-pyrrolidin-1-yl}-butoxy)-acetic acid methyl ester (2.4 mg, 0.006 mmol), rabbit liver esterase (1 mg, 134 units/mg), pH 7.2 phosphate buffer (2.5 mL) and acetonitrile (0.1 mL) was stirred together at rt for 18 h. Acetonitrile (5 mL) was then added and the mixture was concentrated in vacuo to dryness. The residue was purified by flash column chromatography (0%→10% MeOH/CH2Cl2) to afford 1.1 mg (47%) of (4-{(R)-2-[(E)-4-(3-chlorophenyl)-3-oxo-but-1-enyl]-5-oxo-pyrrolidin-1-yl}-butoxy)-acetic acid.
