Versuchsvorschrift

To a mixture of racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-[5-iodo-2-(2-hydroxy-ethoxy)-phenyl]spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (0.1 g, 0.16 mmol) prepared in Example 190c in triethylamine (0.8 mL) was added trimethylsilyl cyanide (23.8 mg, 0.24 mmol) (Aldrich), Tetrakis(triphenylphosphine)palladium (3.7 mg, Aldrich) sequentially. The reaction mixture was refluxed under nitrogen for 2 h. After cooled to room temperature, the reaction mixture was partitioned between saturated water and ethyl acetate. The aqueous layer was extracted with ethyl acetate. The combined organic layer was dried over Na2SO4 and concentrated. The residue was purified by chromatography (EtOAc) to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-[5-cyano-2-(2-hydroxy-ethoxy)-phenyl]spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (Yield 38 mg, 46%).
