Procedure

To a mixture of racemic(2′R, 3R, 4′S)-2′-[5-bromo-2-(1-ethoxycarbonyl-1-methyl-ethoxy)-phenyl]-6-chloro-4′-(3-chlorophenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (700 mg, 1.08 mmol) in methanol (20 mL) was added a solution of NaOH (120 mg, 3 mmol) in water (10 mL). The mixture was heated at 60° C. for 1.5 h, evaporated to remove methanol, cooled to room temperature, and acidified to “pH” 2 with HCl aq. The precipitate was collected, washed with water and dried to give the title compound as a white solid (610 mg).
