Procedure

In a manner similar to the method described in Example 5, rac-(2′S,3′R,4′S,5′R)-4′-(3-bromo-2-fluoro-phenyl)-6-chloro-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid trifluoroacetic acid prepared in Example 97 (0.4 g, 0.66 mmol), was reacted with diisopropylethylamine (0.43 g, 3.3 mmol), diphenylphosphinic chloride (0.31 g, 1.3 mmol), then reacted with 4-amino-3-methoxy-benzonitrile prepared in Example 57 (0.29 g, 2.0 mmol) to give rac-(2′S,3′R,4′S,5′R)-4′-(3-bromo-2-fluoro-phenyl)-6-chloro-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid (4-cyano-2-methoxy-phenyl)-amide as a white foam (Yield 0.17 g, 40%).
