YieldReaction ConditionsOperation in experiment
With N-chloro-succinimide; In dichloromethane; N,N-dimethyl-formamide; at 20℃; Step A: tert-butyl 5 -chloro-2-oxospiro [indoline-3 ,3 ?-pyrrolidinel- 1 ?-carboxylateTo a stirred solution tert-butyl 2-oxospiro[indoline-3,3?-pyrrolidine]-i?-carboxylate (800 mg,2.77 mmol) in dichioromethane (40 mL) and DMF (4 mL) was added N-chlorosuccinimide and the mixture was allowed to stir at room temperature overnight. Aqueous NaHCO3 was added and the mixture was extracted with EtOAc. The organic layer was washed with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by ISCO (40g, EtOAc/Hex= 1 / 1) to give tert-butyl 5 -chloro-2-oxospiro [indoline-3 ,3 ?-pyrrolidine]- 1 ?-carboxylate. [M+ 1] =324.
