6-Isopropoxy-1H-indol-5-ol described in Production Example 17-4 (165 mg, 0.863 mmol) and N-(4-chloropyridin-2-yl)acetamide described in Production Example 1-5 (442 mg, 2.59 mmol) were dissolved in dimethylsulfoxide (2.0 mL) under nitrogen atmosphere, then potassium tert-butoxide (194 mg, 1.73 mmol) was added at room temperature, and the mixture was heated and stirred at 160° C. for 3 hours. The reaction liquid was cooled to room temperature and water and ethyl acetate were added for partition. The aqueous layer was extracted with ethyl acetate and the combined organic layer was washed with water and a saturated saline solution. The organic layer was dried over anhydrous magnesium sulfate and then filtered, then the filtrate was concentrated under vacuum. The residue was dissolved in dichloromethane, the resultant was purified with NH silica gel column chromatography (n-heptane:ethyl acetate=3:2-1:3), and then the target fraction was concentrated under vacuum to obtain the title compound (116 mg, 41%).
