Procedure

In a manner similar to the method described in Example 27, rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-4-fluoro-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid trifluoroacetic acid prepared in Example 71 (0.4 g, 0.67 mmol), was reacted with diisopropylethylamine (0.69 g, 5.4 mmol), diphenylphosphinic chloride (0.63 g, 2.7 mmol) in 1,2-dichloroethane at room temperature, then reacted with 4-aminobenzonitrile (Aldrich) (0.24 g, 2.1 mmol) at 80° C. to give rac-(2′S,3′R,4′S,5′R)-6-chloro-4′-(3-chloro-2-fluoro-phenyl)-2′-(2,2-dimethyl-propyl)-4-fluoro-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (4-cyano-phenyl)-amide as a white solid (Yield 0.2 g, 51%).
