Procedure

In a manner similar to the method described in example 4d, racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(3-fluoro-2-methyl-phenyl)-2,3-dihydro-2,6′-dioxospiro[indole-3,3′-piperidine]-1-carboxylic acid ethyl ester (0.35 g, 0.65 mmol) was reacted with NaOH (2N, 5 mL, 10 mmol) in methanol to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(3-fluoro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (Yield 0.25 g, 83%).
