Versuchsvorschrift

A solution of racemic (2′S,3S,4′R)-6-chloro-4′-[5-chloro-2-(1-ethyl-1-hydroxycarbonyl-propoxy)-phenyl]-2′-(5-chloro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (150 mg, 0.244 mmol) and CDI (80 mg, 0.49 mmol) in DMF (2 mL) was heated at 60° C. for 2 h, then cooled to room temperature. In a separate flask a mixture of methanesulfonamide (231 mg, 2.44 mmol) and NaH (78 mg, 60%, 1.95 mmol) was stirred in DMF (3 mL) at room temperature for 2 h, then the resulting mixture was added into the above solution. The reaction mixture was stirred at room temperature for 1 h, then poured into water and “pH” was acidified to 2-3 by addition of concentrated HCl solution. The mixture was extracted with EtOAc twice, the combined extracts were dried over anhydrous Na2SO4, concentrated and the residue was purified by flash column to give the title compound as a white solid (10 mg).
