Procedure

To the solution of rac-(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-carboxylic acid [4-(2-bromo-acetyl)-phenyl]-amide (30 mg, 0.045 mmol) in tetrahydrofuran (1 mL) was added a tetrahydrofuran solution (2 M) of dimethylamine (0.057 mL, 0.11 mmol). The reaction mixture was stirred at room temperature for 30 min. The mixture was concentrated, and the residue was partitioned between ethyl acetate and water. The organic layer was separated, washed with water, brine, dried over MgSO4, and concentrated to give rac-(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-carboxylic acid [4-(2-dimethylamino-acetyl)-phenyl]-amide as a yellow solid (10 mg, 35%)
