Procedure

To a solution of rac-4-{[(2R,3S,4R,5S)-3-(5-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-benzoic acid methyl ester prepared in Example 336 (125 mg, 0.21 mmol) in tetrahydrofuran (3 mL) was added an aqueous solution (1 N) of NaOH (3 mL, 3 mmol) and methanol (1 mL). The reaction mixture was heated at 80° C. for 2 h, and the “pH” of the solution was adjusted to 5 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-4-{[(2R,3S,4R,5S)-3-(5-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-benzoic acid as a white solid (90 mg, 73%). HRMS (ES+) m/z Calcd for C30H27Cl2F2N3O3+H [(M+H)+]: 586.1471. found: 586.1473.
