A solution of {(Z)-4-[(R)-2-oxo-5-((E)-3-oxo-oct-1-enyl)-pyrrolidin-1-yl]-but-2-enyloxy}-acetic acid ethyl ester (0.7 g, 1.97 mmol) in 15 mL of ethanol was stirred at 0° C., and 0.082 g NaBH4 was added. The reaction was allowed to come to room temperature and stirred for 7 hours, followed by addition of a solution of hydrochloric acid in methanol (2 M, 1-2 mL) and extraction with ethyl acetate. The organic phase was dried, concentrated, purified via chromatography to yield {(Z)-4-[(R)-2-((E)-3-hydroxy-oct-1-enyl)-5-oxo-pyrrolidin-1-yl]-but-2-enyloxy}-acetic acid ethyl ester, and taken directly on to the next step.
