Versuchsvorschrift
Free base of the titled compound was prepared from N-(2-pyridyl)-o-phenylenediamine and (E)-3-chlorocinnamoyl chloride (Amino, Y.; Kawada, K.; Toi, K.; Kumashiro, I.; Fukushima, K. Chem. Pharm. Bull., 1988, 36, 4426) according to the preparation of (E)-1-(2-pyridyl)-2-styryl-1H-benzimidazole (Example 1, method A). The free base was dissolved with a 10% methanol solution of hydrogen chloride (5 ml). Concentration and recrystallization from ethyl acetate/ethanol yielded the titled compound.
