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, 300 mg, 487 μmol) and 2-chloro-N-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)acetamide (101 mg, 487 μmol) were combined with dry dimethyl formamide (5 mL) 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 methanol in ethyl acetate) 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 [(2,2-dimethyl-[1,3]dioxolan-4-ylmethyl)-carbamoyl]-methyl ester as an off-white solid (92 mg, 24% yield). LCMS (ES+) m/z calcd. for C39H42Cl2F2N4O7 [(M+H)+]: 787. found: 787.
