It is maintained at 60° C. for 5 hours, then it is poured into water, extracted with diethyl ether and the extracts washed thoroughly with water, filtered on charcoal, made anhydrous on sodium sulphate and evaporated to dryness. The residue is chromatographied on silica gel column eluting with chloroform:methyl alcohol (9:1) and it gives 1-(2-ethoxyethyl)-2-(3-dimethylaminopropyl)benzimidazole.
