실험 절차

To a solution of rac-4-{[(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}-3-methylamino-benzoic acid methyl ester (0.22 g, 0.35 mmol) in MeOH (4 mL) and THF (12 mL) was added an aqueous solution (1N) of NaOH (7.5 mL, 7.5 mmol). The reaction mixture was stirred at room temperature for 18 h. The crude mixture was diluted with water, and acidified to “pH” 5-6 by dilute aqueous HCl solution. The mixture was then extracted with ethyl acetate three times. The combined organic extract was washed with water, brine, dried over MgSO4, and concentrated. The residue was triturated with dichlormethane and hexanes to give rac-4-{[(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}-3-methylamino-benzoic acid as a off white solid (Yield, 18 mg, 8%).
