1′-[6-(3-Methyl-1,2,4-oxadiazol-5-yl)pyridazin-3-yl]spiro[indole-3,3′-pyrrolidin]-2(1H)-one (300 mg) obtained in Example 158 was dissolved in N,N-dimethylformamide (10 mL), sodium hydride (60 w %, 35 mg) was added, and the mixture was stirred at room temperature for 30 min. Iodomethane (0.054 mL) was added, and the mixture was further stirred at room temperature for 3 hr. The reaction was quenched with saturated aqueous ammonium chloride solution, and water (20 mL) was added. The resulting precipitate was collected by filtration to give the object product (198 mg, 64%).
