Procedure
In a 15 mL pressure tube, 4-((2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamido)-3-methoxybenzoic acid (prepared as described in US20100152190A1, 100 mg, 162 μmol) and cesium carbonate (63.4 mg, 195 μmol) were combined with dimethyl formamide (2 mL). 2-Chloroacetamide (15.2 mg, 162 μmol) was added to the mixture with stirring to give a white suspension. The tube was capped and heated at 50° C. overnight. The reaction mixture was cooled down to room temperature. It was poured into water and extracted with ethyl acetate (2×). The ethyl acetate layers were combined, dried over anhydrous sodium sulfate, filtered and concentrated. The residue was purified with flash chromatography (24 g pre-packed silica gel column, eluted with ethyl acetate in hexanes) to give 4-{[(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}-3-methoxy-benzoic acid carbamoylmethyl ester as an off-white solid (62 mg, 58% yield). LCMS (ES+) m/z calcd. for C33H33Cl2F2N4O5 [(M+H)+]: 673. found: 673.
