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 (0.3 g, 0.52 mmol), was reacted with diisopropylethylamine (0.34 g, 2.7 mmol), diphenylphosphinic chloride (0.35 g, 1.1 mmol), then reacted with 4-aminobenzonitrile (Aldrich) (0.13 g, 1.1 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-cyano-phenyl)-amide as a off white foam (Yield 0.12 g, 41%).
