반응 단계
Free base of the titled compound was prepared from 2-methyl-1-(2-pyridyl)-1H-benzimidazole and 2-imidazolcarboxaldehyde according to the preparation of (E)-1-(2-pyridyl)-2-[2-(2-pyridyl)ethenyl]-1H-benzimidazole dihydrochloride (Example 44). The free base and oxalic acid were dissolved into MeOH. Concentration and recrystallization from ethyl EtOH/n-hexane yielded the titled compound.
