HCID 53237984(4-{[(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'-carbonyl]amino}-3-methoxy-phenyl)-acetic acid tert-butyl ester

Procedure

In a manner similar to the method described in Example 5, chiral (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 136 (0.4 g, 0.69 mmol), was reacted with diisopropylethylamine (0.45 g, 3.5 mmol), diphenylphosphinic chloride (0.49 g, 2.1 mmol), then reacted with (4-amino-3-methoxy-phenyl)-acetic acid tert-butyl ester prepared in Example 158 (0.25 g, 1 mmol) to give chiral (4-{[(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′-carbonyl]amino}-3-methoxy-phenyl)-acetic acid tert-butyl ester as a off white solid (Yield 0.18 g, 38%).
