In the same manner as described in Example 1 using 2-chloro-1-[2-(phenoxy)ethyl]benzimidazole (3.00 g), N-methylpiperazine (3.00 g) and fumaric acid (2.14 g), there are obtained crude crystals, which are recrylstallized from ethyl acetate-ethanol to give 1-[2-(phenoxy)ethyl]-2-(4-methyl-1-piperazinyl)benzimidazole.3/2 fumarate (2.99 g) as pale yellow plates, m.p. 152°-153.5° C.
