Procedure
The ester was taken directly to the hydrolysis step by dissolved in THF (3 mL) and methanol (1 mL), then 2N LiOH (1 mL) was added and stirred at room temperature for 3 hours. The mixture was diluted with water and ethyl acetate, the organic phase was separated then concentrated under reduced pressure to rac-1-{[(2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carbonyl]-amino}-cyclopropanecarboxylic acid (65.2 mg, 67.2%) as an off-white powder. HRMS (ES+) m/z Calcd for C27H27Cl2F2N3O3+H [(M+H)+]: 550.1471. found: 550.1471.
