Product 1

HCID 75985808rac-(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-chloro-phenyl)-amide

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 (0.2 g, 0.36 mmol), was reacted with diisopropylethylamine (0.18 g, 1.4 mmol), diphenylphosphinic chloride (0.25 g, 1.1 mmol), then reacted with 4-chloroaniline (Fluka) (0.054 g, 0.43 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-chloro-phenyl)-amide as a off white solid (Yield 95 mg, 47%).
