Procedure

At room temperature, a mixture of racemic (2′S,3S,4′R)-6-chloro-4′-[5-chloro-2-(1-ethyl-1-hydroxycarbonyl-propoxy)-phenyl]-2′-(5-fluoro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (50 mg, 0.084 mmol) prepared in Example 62h, dimethylamine hydrochloride (13.5 mg, 0.17 mmol), HATU (63.5 mg, 0.17 mmol) and DMAP (40.8 mg, 0.33 mmol) in DMF (2 mL) was stirred for 5 h. Then the mixture was poured into water and extracted with EtOAc thrice. The combined organic phases were washed with brine twice, dried over anhydrous Na2SO4 and concentrated. The residue was purified by flash column to give the title compound as a white solid (40 mg).
