実験手順

To the solution of acetic acid rac-3-[(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-5′-(4-cyano-phenylcarbamoyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidin]-2′-yl]-2,2-dimethyl-propyl ester prepared in Example 104 (80 mg, 0.13 mmol) in DMSO (0.5 mL) at 0° C. was added an aqueous solution (30% Aldrich) of H2O2 (0.22 g, 1.9 mmol), then aqueous solution (1N) of NaOH (0.64 mL, 0.64 mmol) was added dropwise. The reaction mixture was stirred at room temperature for 5 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 to 100% EtOAc in CH2Cl2) to give rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′43-hydroxy-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 73 mg, 95%)
