Reaction Steps

To a solution of 7-{(R)-2-[(E)-3-(3-bromo-phenyl)-3-oxo-propenyl]-5-oxo-pyrrolidin-1-yl}-heptanoic acid methyl ester (0.78 g, 1.79 mmol) in 15 mL of methanol stirred at 0° C. under nitrogen was added sodium borohydride (0.074 g). The reaction mixture was stirred at room temperature for 6 hours. After addition of 1 N HCl solution the mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and purified by chromatography eluting with 50% EtOAc and Hexane followed by 100% EtOAc to yield 670 mg of 7-{(R)-2-[(E)-3-(3-bromo-phenyl)-3-hydroxy-propenyl]-5-oxo-pyrrolidin-1-yl}-heptanoic acid methyl ester.
