Participants

Reaction Steps

A mixture of (4-{(R)-2-[4-(3-chlorophenyl)-3-oxo-butyl]-5-oxo-pyrrolidin-1-yl}-butoxy)-acetic acid methyl ester (8.1 mg, 0.02 mmol), rabbit liver esterase (1 mg, 134 units/mg), pH 7.2 phosphate buffer (3 mL) and acetonitrile (0.1 mL) was stirred together at rt for 16.5 h. Aqueous HCl (0.5 M, 5 mL) was added and the mixture was extracted with CH2Cl2 (3×5 mL). The combined organic phase was dried (Na2SO4), filtered and concentrated in vacuo to afford 1.6 mg (20%) of (4-{(R)-2-[(E)-4-(3-chlorophenyl)-3-oxo-but-1-enyl]-5-oxo-pyrrolidin-1-yl}-butoxy)-acetic acid.
