Selective mono tosylation by using tosyl chloride in presence of base, TEA for 72 h at 4 o C, isolated the mono-tosylated product 3, which successfully converted to iodo product 4 in 70% yield, under reflux condition with sodium Iodide in acetone. The mono viologen 5, is obtained 88 yield by following the modified procedure. Treating the mono viologen 5 with iodo compound 4 in presence of DCC reagent to obtain the salt, which was characterized by NMR and Mass.
