Procedure
In a similar manner as in Example 2, 6-chloro-3-(4-methoxyphenyl)-4-phenylpyridazine (215 mg, 0.725 mmol) and 2,4-difluorophenol were reacted as starting materials at 150° C. for 20 hours and post-treatment was then conducted, whereby the title compound was obtained as colorless needles (169.7 mg, 60.0%). Melting point: 169.0-169.9° C. (ethyl acetate-hexane).
