Procedure

2-Ethyl-1-[2-(2-methoxyethoxy)ethyl]-1H-benzimidazole was synthesized as in Synthesis Example 1 except that an equimolar amount of 2-ethylbenzimidazole was used instead of benzimidazole and an equimolar amount of 2-chloroethyl 2-methoxyethyl ether was used instead of 2-chloroethyl methyl ether. Yield 77%.
