Reaction Steps

In the same manner as described in Reference Example 4, N-benzylpiperazine (20 g) and 2-chloromethylbenzimidazole (9.0 g) are reacted, and the crude crystal thus obtained is recrystallized from ethyl acetate to give 2-(4-benzyl-1-piperazinyl)methylbenzimidazole (13.8 g) as pale yellow needles, m.p. 195°-201° C.
