34.3 g (0.22 mol) of 4,4′-bipyridyl and 106 g (0.66 mol) of α,α′-dichloro-p-xylene are stirred in 500 ml of acetonitrile at 90° C. for 4 hours under an argon atmosphere. After cooling, the precipitate is filtered off and washed sufficiently with acetonitrile. Drying gives 88.1 g of 1,1′-di[p-(chloromethyl)benzyl]-4,4′-bipyridinium dichloride.
