Versuchsvorschrift

To the solution of rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (6-cyano-pyridin-3-yl)-amide (0.12 g, 0.2 mmol) prepared in Example 182 in DMSO (2 mL) at 0° C. was added an aqueous solution (30% Aldrich) of H2O2 (0.36 g, 3 mmol), then aqueous solution (1N) of NaOH (1 mL, 1 mmol) was added dropwise. The reaction mixture was stirred at 0° 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. The residue was purified by chromatography (50-100% EtOAc in dichloromethane) to give rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (6-carbamoyl-pyridin-3-yl)-amide as a white solid (Yield 80 mg, 65%)
