Procedure

1-(4-Cyanophenyl)benzimidazole (90 g, slightly contaminated with mineral oil) together with THF (250 ml) is placed in a reaction vessel, admixed with methyl iodide (116 g, 0.82 mol) and maintained at 40° C. for 25.5 hours. The residue formed is filtered off, washed with ethanol and dried under reduced pressure. This gives 123 g of 1-(4-cyanophenyl)-3-methylbenzimidazolium iodide.
