Reaction Steps

In the preparation of chiral (2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid [4-(2-methanesulfonyl-ethoxy)-2-methoxy-phenyl]-amide in Example 170, the second product chiral (2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid [4-(2-methanesulfinyl-ethoxy)-2-methoxy-phenyl]-amide was obtained by chromatography (10% MeOH in EtOAc) as a yellow solid (Yield 63 mg, 36%).
