Procedure

In a manner similar to the method described in Example 2, racemic(2′R, 3R, 4′S)-6-chloro-4′-(3-chlorophenyl)-2′-[5-Iodo-2-(tetrahydro-pyran-4-yloxy)-phenyl]spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (1.3 g, 1.97 mmol) was reacted with trimethylsilyl acetylene (0.4 g, 3.94 mmol), CuI (0.75 g, 3.94 mmol), triethylamine (0.4 mL, 3.94 mmol) and dichlorobis(triphenylphosphine) palladium(0) (0.28 g, 0.39 mmol), then treated with aqueous NaOH solution in methanol to give racemic(2′R, 3R, 4′S)-6-chloro-4′-(3-chlorophenyl)-2′-[5-ethynyl-2-(tetrahydro-pyran-4-yloxy)-phenyl]spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as an off white solid (Yield 0.62 g, 56%).
