Participants

Reaction Steps

In a manner similar to the method described in example 1c, E/Z-6-methoxy-3-(3-chloro-benzylidene)-2-oxo-2,3-dihydro-indole (0.4 g, 1.10 mmol) prepared in example 168b was reacted with 1-(5-fluoro-2-methylphenyl)-3-trimethylsilyoxy-2-aza-1,3-butadiene prepared in example 36a, in toluene to give racemic (2′R,3R,4′S)-4′-(3-chlorophenyl)-2′-(5-fluoro-2-methylphenyl)-6-methoxy spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (Yield 0.05 g, 10%).
