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 (100 mg, 0.173 mmol), was reacted with diisopropylethylamine (111 mg, 0.86 mmol), diphenylphosphinic chloride (106 mg, 0.446 mmol), then reacted with 5-Amino-benzo[b]thiophene-2-carboxylic acid methyl ester (Maybridge, 41 mg, 0.190 mmol) to give rac-5-{[(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}-benzo[b]thiophene-2-carboxylic acid methyl ester (49 mg, 43%). MS (ES+) m/z [(M+H)+]: 654
