Reaction Conditions

Reaction Steps

A mixture containing 0.900 g of 2,4-dimethyl-6-methoxycarbonylbenzimidazole, 1.20 g of 2,4-dichlorobenzyl chloride, 0.200 g of sodium iodide, 0.610 g of potassium carbonate and 4 ml of N,N-dimethylformamide was stirred at 80° C. for 16 hours. After the organic solvent was distilled off under reduced pressure, the residue was extracted with ethyl acetate and with water. The organic layer was concentrated, and was crystallized with the addition of hexane. The crystals were separated through filtration, and were dried to give 1.08 g of 1-(2,4-dichlorobenzyl)-2,4-dimethyl-6-methoxycarbonylbenzimidazole (353).
