Procedure

A mixture of chiral 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoic acid (100.2 mg, 0.164 mmol) and N,N′-carbonyldiimidazole (68.8 mg, 0.424 mmol, Aldrich) in tetrahydrofuran (5 mL) was stirred at room temperature overnight. N,N-dimethylethanolamine (44.3 mg, 0.495 mmol, Aldrich) was added to a suspension of sodium hydride (12 mg, 0.475 mmol) in tetrahydrofuran (4 mL) and stirred at room temperature for 1 h. It was then added to the above mixture and stirred at room temperature for 1 h. The reaction mixture was quenched with water and extracted with ethyl acetate. The organic layer was washed with water, brine and dried over anhydrous sodium sulfate and concentrated. the crude product was purified by flash chromatography to give chiral 2-(dimethylamino)ethyl 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoate as a white solid (97.2 mg, 86% yield). MS (ES+) m/z calcd. for C35H39Cl2F2N4O4 [(M+H)+]: 687. found: 687.
