Procedure

In a manner similar to the method described in example 193, racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(5-iodo-2-nitrophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione prepared in example 201c (0.36 g, 0.59 mmol) was reacted with trimethylsilyl acetylene (120 mg, 1.18 mmol), CuI (0.23 g, 1.18 mmol), triethylamine (120 mg, 1.18 mmol), and dichlorobis(triphenylphosphine)palladium(0) (83 mg, 0.118 mmol) in anhydrous tetrahydrofuran, and then treated with aqueous NaOH in methanol to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(5-ethynyl-2-nitrophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (Yield 0.25 g, 84%)
