実験手順
Free base of the titled compound was prepared from 2-methyl-1-(2-pyridyl)-1H-benzimidazole and pyridine-3-carboxaldehyde 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 MeOH/EtOH yielded the titled compound.
