実験手順
109 mg (0.382 mmol) of (2,4-dichlorophenyl)(5-hydroxy-1,3-dimethyl-1H-pyrazol-4-yl)methanone, 1.62 g (6.35 mmol) of 4,6-dichloro-3-(2-methylphenoxy)pyridazine obtained in Example 1 (2) and 107 mg (0.775 mmol) of potassium carbonate were mixed, and the mixture was stirred at 130° C. for 14 hours. The reaction mixture was cooled up to room temperature, and purified by silica gel column chromatography (hexane:ethyl acetate, gradient) to obtain 155 mg (0.308 mmol, Yield: 80.6%) of (5-{[5-chloro-6-(2-methylphenoxy)-3-pyridazinyl]oxy}-1,3-dimethyl-1H-pyrazol-4-yl)(2,4-dichlorophenyl)methanone.
