Reaction Steps

In a manner similar to the method described in Example 380, chiral 6-({[(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)-nicotinic acid ethyl ester (73.8 mg, 0.117 mmol) in THF (8 ml) was combined with lithium hydroxide hydrate (35.9 mg, 0.855 mmol) in water (4 mL). It was stirred at room temperature to give chiral 6-({[(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)-nicotinic acid as a white lyophilized solid (71.3 mg, 100%). HRMS (ES+) m/z Calcd C30H28Cl2F2N4O3+H [(M+H): 601.1580. Found: 601.1581.
