Procedure

To a mixture of the above 1-iodoethyl acetate (311 mg, 1.457 mmol) and 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 (US20100152190A1, 201.7 mg, 0.327 mmol) in dimethylformamide (6 mL) was added cesium carbonate (659 mg, 2.00 mmol) and the mixture was stirred at room temperature for 16 h. The reaction mixture was taken up in ethyl acetate, washed with water and then brine. The organic layer was dried over sodium sulfate and concentrated to dryness. The crude material was purified by flash chromatography (hexane/ethyl acetate, 80/20 to 20/80) to give 1-acetoxyethyl 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoate (149.4 mg, 65% yield). MS (ES+) m/z calcd. for C35H36Cl2F2N3O6: [(M+H)+]: 702.19, found: 702.4
