Procedure

To the solution of racemic(2′R, 3R, 4′S)-2′-[5-bromo-2-(4-hydroxycarbonyl-phenoxy)-phenyl]-6-chloro-4′-(3-chlorophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (0.18 g, 0.28 mmol) in dichloromethane (50 mL) at 0° C. was added cyanuric fluoride (120 mg, 0.88 mmol) (Alfa) and pyridine (100 mg, 1.3 mmol). After the mixture was stirred at 0° C. for 2 h, the mixture was partitioned between H2O and dichloromethane. The organic layer was separated and the aqueous layer was extracted with dichloromethane. The organic layers were combined, dried over MgSO4, concentrated to give racemic(2′R, 3R, 4′S)-2′-[5-bromo-2-(4-fluorocarbonyl-phenoxy)-phenyl]-6-chloro-4′-(3-chlorophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a yellow foam and used for the next step without further purification (Yield: 0. 18 g, 98%).
