To a stirred solution of racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-[2-(2,3-dihydroxy-propoxy)-5-iodo-phenyl]spiro[3H-indole-3,3′-piperidine]-2,6′-dione (120 mg, 0.183 mmol) in DMF (2 mL) were added PdCl2(PPh3)2 (15 mg), CuI (2 mg), trimethylsilyl acetylene (Aldrich, 2 mL) and Et3N (Aldrich, 2 mL) and the mixture was purged with nitrogen and then heated at 75° C. for 3 hrs. The mixture was partitioned between ethyl acetate and water. The organic layer was separated, washed with water, brine, dried, and concentrated. The residue was purified by chromatography (0-4% MeOH in EtOAc). Yield 8 mg. MS (H+), 623
