Versuchsvorschrift

To a mixture of rac-4-{[(2S,3S,4S)-2,3-bis-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carbonyl]-amino}-benzoic acid methyl ester (142.6 mg, 0.24 mmol) in THF/MeOH (3.4 mL/0.8 mL) was added 4 N LiOH (1.4 mL), and the reaction mixture was stirred at rt overnight. The reaction mixture was concentrated and quenched with 2 NH2SO4, extracted with EtOAc, and washed with water, brine. The organic phase was separated, and dried over Na2SO4. The mixture was then concentrated to give rac-4-{[(2S,3S,4S)-2,3-bis-(4-chloro-2-fluoro-phenyl)-3-cyano-4-(2,2-dimethyl-propyl)-pyrrolidine-1-carbonyl]-amino}-benzoic acid (111.6 mg, 80.6%). HRMS (ES+) m/z Calcd for C30H27Cl2F2N3O3+H [(M+H): 586.1471; Found: 586.1472.
