Reaction Steps

A mixture of racemic (2′S, 3S, 4′R)-6-chloro-4′-[5-chloro-4-fluoro-2-(1-methoxycarbonyl-1-methyl-ethoxy)-phenyl]-2′-(5-fluoro-2-methyl-phenyl) spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (40 mg, 0.067 mmol) and P2S5 (45 mg, 0.20 mmol) in THF (2 mL) was heated at 50° C. for 2 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 (26 mg).
