Reaction Steps

In a manner similar to the method described in Example 9, rac-(2′S,3′S,4′S)-6-chloro-2′-(3-chloro-2-fluoro-phenyl)-4′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-1′-carbonylchloride prepared in Example 8 (57 mg, 0.12 mmol) was reacted with C-(1,3-dimethyl-1H-pyrazol-4-yl)methylamine (Oakwood) (22 mg, 0.18 mmol) and triethylamine to give rac-(2′S,3′S,4′S)-6-chloro-2′-(3-chloro-2-fluoro-phenyl)-4′-(2,2-dimethyl-propyl)-2-oxo-1,2-dihydro-spiro[indole-3,3′-pyrrolidine]-1′-carboxylic acid (1,3-dimethyl-1H-pyrazol-4-ylmethyl)-amide as a white solid (Yield, 19 mg, 28%).
