Reaction Steps

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 (0.4 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 2-methoxy-4-(morpholinosulfonyl)aniline (Matrix) (0.29 g, 1.1 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 [2-methoxy-4-(morpholine-4-sulfonyl)-phenyl]-amide as a white solid (Yield 0.04 g, 8%).
