Versuchsvorschrift

To the solution of rac-(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-5-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (4-cyano-phenyl)-amide (0.12 g, 0.2 mmol) prepared in Example 88 in DMSO (1 mL) at 0° C. was added an aqueous solution (30% Aldrich) of H2O2 (0.36 g, 3.2 mmol), then aqueous solution (1N) of NaOH (1.1 mL, 1.1 mmol) was added dropwise. The reaction mixture was stirred at 10° C. for 1 h. The mixture was partitioned between ethyl acetate and saturated aqueous Na2SO3 solution. The organic layer was separated, washed with water, brine, dried over MgSO4, and concentrated to give rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-5-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (4-carbamoyl-phenyl)-amide as a white solid (Yield 66 mg, 53%)
