Procedure

To a solution of rac-5-{[(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-furan-2-carboxylic acid methyl ester prepared in Example 144 (80 mg, 0.14 mmol) in tetrahydrofuran (2 mL) was added an aqueous solution (2 mL) of LiOH (32 mg, 1.35 mmol). The reaction mixture was stirred at room temperature for 66 h, and the “pH” of the solution was adjusted to 5-6 by aqueous HCl solution. The mixture was extracted ethyl acetate twice. The combined organic extracts were washed with water, brine, dried over MgSO4, and concentrated to give rac-5-{[(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-furan-2-carboxylic acid as a yellow solid (60 mg, 74%).
