Reaction Steps

A mixture of 4-styrylpyridine (0.181 g) and 1,4-dibromobutane (0.432 g) in ethylacetate (5 ml) was stirred and refluxed for 24 hours, and then filtered. The crystals obtained were washed and dried to give 0.31 of N-(4-bromobutyl)-4-styrylpyridinium bromide λmax of 344 nm (water). NMR (CDCl3, p.p.m.): 9.4(d.,2H), 8.0(d.,2H), 7.0-7.7(m.,7H), 4.9(T.,2H), 3.4(m.,2H), 2.0(m.,4H).
