Procedure

In a manner similar to the method described in example 193, racemic (2′S,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(2-fluoro-5-iodophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione prepared in example 194b (0.45 g, 0.77 mmol) was reacted with trimethylsilyl acetylene (1.1 mL, 7.7 mmol), CuI (10 mg), triethylamine (3.22 mL, 23 mmol), and dichlorobis(triphenylphosphine)palladium (54 mg, 0.077 mmol) in anhydrous N,N-dimethylformamide, 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-fluoro-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a light brown solid (Yield 57 mg)
