Versuchsvorschrift

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 {1-[2-(tert-butyl-dimethyl-silanyloxy)-ethyl]-2-oxo-1,2-dihydro-pyridin-4-yl}-amide (0.1 g, 0.14 mmol) in tetrahydrofuran (3 mL) was added aqueous HCl solution (1N, 3 mL, 3 mmol). The reaction mixture was stirred at room temperature for 1 h. The mixture was concentrated. The residue was partitioned between ethyl acetate and aqueous saturated NaHCO3 solution. The organic layer was separated, washed with water, brine, dried over Na2SO4, then concentrated. The residue was purified by chromatography (10-15% of MeOH in EtOAc) 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 (2-oxo-1-propyl-1,2-dihydro-pyridin-4-yl)-amide as a white solid (Yield, 12 mg, 14%).
