Reaction Steps

In a manner similar to the method described in Example 5, 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 trifluoroacetic acid prepared in Example 136 (0.2 g, 0.35 mmol), was reacted with diisopropylethylamine (0.22 g, 1.7 mmol), diphenylphosphinic chloride (0.16 g, 0.7 mmol), then reacted with 4-(3-methanesulfonyl-propoxy)-2-methoxy-phenylamine prepared in Example 180 (0.13 g, 0.5 mmol) to give 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-(3-methanesulfonyl-propoxy)-2-methoxy-phenyl]amide as a yellow solid (Yield 0.13 g, 51%).
