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-4-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 82 (0.4 g, 0.69 mmol) was reacted with diisopropylethylamine (0.46 g, 3.6 mmol), diphenylphosphinic chloride (0.34 g, 1.4 mmol), then reacted with methyl 4-amino-3-methoxybenzoate (Ark Pharm) (0.19 g, 1.07 mmol) to give rac-4-{[(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-4-fluoro-phenyl)-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%).
