Acetyl chloride → 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-acetylamino-2-methoxy-phenyl)-amide

To a solution of 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-amino-2-methoxy-phenyl)-amide (17 mg, 0.029 mmol) and triethylamine (4 mg, 0.044 mmol) in THF (2 mL) was acetyl chloride (2.3 mg, 0.029 mmol). The reaction mixture was stirred at room temperature for 1 h. The mixture was concentrated. The residue was partitioned between ethyl acetate and water. The organic layer, was separated, and aqueous layer was extracted with ethyl acetate. The combined organic extract was washed with water, brine, dried over MgSO4, and concentrated 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-acetylamino-2-methoxy-phenyl)-amide as a off white solid (17 mg, 93%).
