Procedure

To a mixture of racemic (2′S,3S,4′R)-4′-[5-bromo-2-(1-ethoxycarbonyl-1-methyl-ethoxy)-phenyl]-6-chloro-2′-(5-fluoro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (120 mg, 0.19 mmol) in methanol (4 mL) was added a solution of NaOH (24 mg, 0.6 mmol) in water (2 mL). The mixture was heated at 70° C. for 3 h, evaporated to remove most of methanol, cooled to room temperature, and acidified to “pH” 1 with aqueous HCl solution. The precipitate was collected and dried to give product as a white solid (75 mg). m/z (M+H)+: 615
