Procedure
A solution of 3-[(4'-fluorobiphenyl-4-sulfonyl)-(1-hydroxycarbamoylcyclopentyl)amino]-propionic acid methyl ester (8.9 grams, 19.2 mmole) in methanol (500 mL) was treated with aqueous 1 N sodium hydroxide solution (95 mL, 95 mmole) and stirred at room temperature for 5.5 hours. The mixture was concentrated to remove methanol, diluted with water, acidified with 6 N aqueous hydrochloric acid solution and extracted with ethyl acetate. After washing with water and brine the organic extract was dried over magnesium sulfate and concentrated to afford 3-[(4'-fluorobiphenyl-4-sulfonyl)-(1-hydroxycarbamoyl-cyclopentyl)amino]propionic acid as a white foam which was crystallized from ethyl acetate (6.74 grams, 78%).
