To a solution of 1.46 g of 5,6-dimethylbenzimidazole dissolved in 50 ml of dry N,N-dimethylformamide was added 0.84 g of NaH, and further, 8.2 ml of 6-chloro-1-hexanol. After the reaction was carried out by stirring the mixture at room temperature for one day, the reaction was stopped by an addition of water. Subsequently, according to the same processes as in Example 1, crude 1-(6-hydroxyhexyl)-5,6-dimethylbenzimidazole was obtained. The conversion to this compound from 5,6-dimethylbenzimidazole was found to be 95% or higher.
