Reaction Steps

In a manner similar to the method described in Example 380, rac-4-({[(2R,3S,4R,5S)-4-(4-chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-methyl)-2-fluoro-benzoic acid methyl ester (80.3 mg, 0.127 mmol) in THF (9 ml) was reacted with lithium hydroxide hydrate (37.6 mg, 0.896 mmol) in water (4.5 mL) to give rac-4-({[(2R,3S,4R,5S)-4-(4-Chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-methyl)-2-fluoro-benzoic acid as a white lyophilized solid (76.5 mg, 97%). HRMS (ES+) m/z Calcd C31H28Cl2F3N3O3+H [(M+H): 618.1533. Found: 618.1533.
