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, 0.69 mmol), then reacted with 2-methoxy-4-(tetrahydro-pyran-4-yloxy)-phenylamine prepared in Example 156 (0.1 g, 0.52 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 [2-methoxy-4-(tetrahydro-pyran-4-yloxy)-phenyl]amide as a off white solid (Yield 0.08 g, 35%).
