Procedure
In a manner similar to the method described in Example 5, rac-(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid trifluoroacetic acid prepared in Example 63 (0.95 g, 1.7 mmol), was reacted with diisopropylethylamine (1.8 g, 14 mmol), diphenylphosphinic chloride (1.6 g, 6.8 mmol), then reacted with 4-aminobenzonitrile (Aldrich) (0.8 g, 6.8 mmol) to give rac-(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-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 white solid (Yield 0.5 g, 54%).
