Reaction Steps

To a methanol solution (5 mL) of 7-{(R)-2-[(E)-3-Hydroxy-3-(2′-methyl-biphenyl-3-yl)-propenyl]-5-oxo-pyrrolidin-1-yl}-heptanoic acid methyl ester (87 mg) was added an aqueous solution (2.5 mL) of LiOH monohydrate. The reaction mixture was stirred for 6 h and then concentrated to remove the methanol. The aqueous concentrate was diluted with CH2Cl2 and 1N HCl was added, extracted with CH2Cl2 and dried over MgSO4. This mixture was filtered and concentrated to yield 62 mg of 7-{(R)-2-[(E)-3-Hydroxy-3-(2′-methyl-biphenyl-3-yl)-propenyl]-5-oxo-pyrrolidin-1-yl}-heptanoic acid as an oil (42) (50).MS:435 [(M+H)+].
