Reaction Steps
To a mixture of ethyl 6-chloronicotinate (2.43 g), 1H-benzimidazole (1.7 g) and potassium carbonate (5.43 g) was added N,N-dimethylformamide (20 mL), and the mixture was stirred at 50° C.-60° C. for 9 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and the solvent was evaporated. The obtained residue was purified by column chromatography (chloroform:methanol) to give the title compound (2.28 g).
