Procedure

To a stirred solution of rac-4-{[(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carbonyl]-amino}-3-methoxy-benzoic acid methyl ester (100 mg, 0.16 mmol) in methanol (10 mL) was added an aqueous solution (2 mL) of NaOH (33 mg, 0.82 mmol). The reaction mixture was stirred at room temperature overnight. The “pH” of the mixture was adjusted to 4.5, and the solvent was reduced to about 3 ml. The mixture was filtered, and the precipitate was collected, dried to give a white solid, which was purified by chromatography (7%-10% methanol/methylene chloride) to give 20 mg desired product. MS (H+), 596.
