実験手順

At room temperature, to a mixture of racemic (2′S,3S,4′R)-6-chloro-4′-[5-chloro-2-(1-ethyl-1-methanesulfonylaminocarbonyl-propoxy)-phenyl]-2′-(5-chloro-2-methyl-phenyl)-spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (400 mg, 0.58 mmol) and acetic anhydride (71 mg, 0.69 mmol) in DCM (20 mL) was added DMAP (7 mg, 0.06 mmol) slowly. After the mixture was stirred for 2 h, the solution was washed by 0.5N HCl solution twice, dried over anhydrous Na2SO4 and concentrated. The residue was purified by Prep-HPLC to give the title compound as a white solid (100 mg).
