Participants

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 (0.2 g, 0.35 mmol), was reacted with diisopropylethylamine (0.22 g, 1.7 mmol), diphenylphosphinic chloride (0.16 g, 0.7 mmol), then reacted with 2-methoxy-N,N-dimethyl-benzene-1,4-diamine prepared in Example 163 (0.07 g, 0.45 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-dimethylamino-2-methoxy-phenyl)-amide as a light yellow solid (Yield 0.12 g, 57%).
