Procedure

A mixture of racemic (2′S, 3S, 4′R)-6-chloro-4′-[5-chloro-2-(1-methoxycarbamoyl-1-methyl-ethoxy)-phenyl]-2′-(5-fluoro-2-methyl-phenyl) spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (25 mg, 0.042 mmol) and Lawesson's reagent (33 mg, 0.084 mmol) in THF (1 mL) was stirred at room temperature for 1 h, and then diluted with toluene (10 mL). The mixture was concentrated and the residue was washed with DCM twice. The DCM solutions were combined and concentrated. The residue was purified by flash column to give the title compound as white solid (10 mg).
