Procedure

In a manner similar to the method described in example 60b, racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-1′-(3-chloro-propyl)-2′-(5-fluoro-2-methylphenyl)-2,3-dihydro-2,6′-dioxospiro[indole-3,3′-piperidine]-1-methoxyethyl trimethylsilane prepared in example 60a (91 mg, 0.134 mmol) was reacted with pyrrolidine (2 mL), trifluoroacetic acid (10 mL) and then N,N′-diisopropylethylamine (2 mL) to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(5-fluoro-2-methylphenyl)-1′-(3-pyrrolidin-1-yl-propyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (21 mg, 26.9%).
