Procedure
A mixture of 3.4 parts of 5-(chloromethyl)-4-methyl-1H-imidazole monohydrochloride, 6 parts of 1-(2-furanylmethyl)-N-(4-piperidinyl)-1H-benzimidazol-2-amine, 4.25 parts of sodium carbonate and 135 parts of N,N-dimethylformamide was stirred and heated for 3 hours at 70° C. The reaction mixture was poured onto water and the product was extracted with trichloromethane. The extract was dried, filtered and evaporated. The residue was crystallized from a mixture of acetonitrile and methanol, yielding 4.7 parts (60.2%) of 1-(2-furanylmethyl)-N-[1-[(4-methyl-1H-imidazol-5-yl)methyl]-4-piperidinyl]-1H-benzimidazol-2-amine; mp. 242.1° C. (compound 1).
