Reaction Steps
In a nitrogen atmosphere, a mixture of 118 g of benzimidazole, 94.5 g of 2-chloroethyl methyl ether, 138 g of potassium carbonate, and 400 g of N,N-dimethylformamide was heated and stirred at 100° C. for 20 hours. The reaction mixture was subjected to conventional aqueous work-up and distillation under reduced pressure for purification, to give 154 g of 1-(2-methoxyethyl)-1H-benzimidazole (boiling point 125° C./33 Pa, yield 87%).
