Reaction Steps

2-Aminomethylpyridine (0.372 g) was added to a solution of 0.597 g of 1-(biphenyl-4-ylmethyl)-6-chloromethyl-2-methylbenzimidazole and 0.350 g of potassium carbonate in 3 ml of N,N-dimethylformamide, and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was extracted with water and with ethyl acetate. The organic layer was washed twice with water, and the solvent was distilled off under reduced pressure. The resulting residue was purified through silica-gel column chromatography (eluent: a mixture of chloroform and methanol at a ratio of 9:1), and was recrystallized from a mixed solvent of ethyl acetate and hexane to give 0.300 g of 1-(biphenyl-4-ylmethyl)-2-methyl-6-[2-pyridylmethyl)aminomethyl]benzimidazole (265).
