Reaction Steps

In a manner similar to the method described in example 30, racemic (2′S,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(2,3-difluoro-6-methylphenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (0.18 g, 0.37 mmol) prepared in example 52c was reacted with 2,4-bis-(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane 2,4-disulfide (0.32 g, 0.96 mmol) in toluene to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(2,3-difluoro-6-methylphenyl)-6′-thioxospiro[3H-indole-3,3′-piperidine]-2(1H)-one (Yield 0.13 g, 69.8%).
