実験手順

A solution of chiral (2′S,3S,4′R)-6-chloro-4′-[5-chloro-2-(1-hydroxycarbonyl-1-methyl-ethoxy)-phenyl]-2′-(5-fluoro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (45 mg, 0.079 mmol) prepared in Example 12a and CDI (26 mg, 0.16 mmol) in DMF (0.5 mL) was heated at 60° C. for 2 h. Then to this solution was added a mixture of cyclopropanesulfonamide (48 mg, 0.4 mmol) and NaH (13 mg, 60%, 0.3 mmol) in DMF (1 mL), which had been stirred for 1 h at room temperature. After the resulting mixture was stirred at room temperature for 1 h, it was poured into water (5 mL) and the aqueous solution was acidified to “PH” 2-3 by addition of concentrated hydrochloride solution. After the aqueous phase 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 (38 mg).
