実験手順

To a solution 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 (prepared as described in US20100152190A1, 150 mg, 0.243 mmol) in dimethylformamide (6 mL) was added cesium carbonate (243 mg, 0.746 mmol). After stirring for a few minutes, a solution of the above freshly made ethyl-isopropyl-carbamic acid 1-chloro-ethyl ester (190 mg, 0.491 mmol) in dry dimethylformamide (1 mL) was added and the reaction mixture was allowed to stir at room temperature overnight. This reaction mixture was diluted with ethyl acetate and washed with water, brine and concentrated to dryness. The crude material was purified by chromatography (hexane/ethyl acetate, 90/10 to 10/90) to give 1-(ethyl(isopropyl)-carbamoyloxy)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 (102 mg, 54% yield). LCMS (ES+) m/z calcd. for C39H45Cl2F2N4O6 [(M+H)−]: 773, found: 773.
