Procedure

In a similar manner as in Example 2, 3,4-bis(4-methoxyphenyl)-6-chloropyridazine (200 mg, 0.613 mmol) and 4-hydroxypyridine were reacted as starting materials at 150° C. for 22 hours and post-treatment was then conducted, whereby the title compound was obtained as a pale yellow crystalline powder (201.6 mg, 85.2%). Melting point: 186.8-188.8° C. (hexane).
