Reaction Steps

A mixture of (2′R,3R,4′S)-2′-[5-bromo-2-(2-methoxycarbonyl-2-methyl-propoxy)-phenyl]-6-chloro-4′-(5-chloro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (50 mg), NaOH (40 mg), H2O (5 mL) and THF (2 mL) was heated at 80° C. for 2 h. Then the mixture was concentrated. The remaining aqueous solution was acidified to “pH” 2 by concentrated aqueous HCl (1.5 mL). The white precipitate was collected by filtration to give the title compound as a white solid (Yield: 20 mg).
