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-phenyl)-2′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-5′-carboxylic acid trifluoroacetic acid prepared in Example 63 (0.28 g, 0.5 mmol), was reacted with diisopropylethylamine (0.38 mL, 2.25 mmol), diphenylphosphinic chloride (0.36 mL, 1.9 mmol), then reacted with methyl 4-amino-3-methoxy-benzoate (Ark Pharm) (0.09 g, 0.5 mmol) to give rac-4-{[(2′S,3′R,4′R,5′R)-6-chloro-4′-(3-chloro-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, 102 mg, 33%).
