実験手順

4-styrylpyridine (1.81 g) and 2-(2-bromoethyl) 1,3-dioxane (1.95 g) were stirred and refluxed in ethylacetate (15 ml) solution for 15 hours. After cooling of the reaction mixture creamy crystals were separated by filtration, washed with ethyl ether and dried to give 3.4 g of N-[2-(1,3-dioxane-2-yl)ethyl]-4-styrylpyridinium bromide.
