Procedure

In a manner similar to the method described in Example 5, rac-(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 4 (0.3 g, 0.52 mmol), was reacted with diisopropylethylamine (0.34 g, 2.6 mmol), diphenylphosphinic chloride (0.38 g, 1.6 mmol), then reacted with N-(4-amino-3-methoxyphenyl)methanesulfonamide hydrochloride (Astatech) (0.2 g, 0.8 mmol) to give rac-(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-methanesulfonylamino-2-methoxy-phenyl)-amide as a yellow solid (Yield 0.16 g, 47%).
