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, 0.64 mmol), was reacted with diisopropylethylamine (0.43 g, 3.3 mmol), diphenylphosphinic chloride (0.31 g, 1.3 mmol), then reacted with methyl 4-amino-3-methoxybenzoate (Ark Pharm) (0.18 g, 0.99 mmol) to give rac-4-{[(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′-carbonyl]amino}-3-methoxy-benzoic acid methyl ester as a white solid (Yield 0.22 g, 51%).
