実験手順

1-Dodecyl-2-methylpyridinium bromide (3.42 g), 0.01 mole) and 4-diethylaminobenzaldehyde (1.9 g), 0.011 mole) were refluxed in ethanol (15 ml) in the presence of piperidine (0.2 ml) under nitrogen for two hours. The solution was cooled and ether was added when an orange solid crystallised which was collected giving 2-[4-(diethylamino)styryl]-1-dodecylpyridinium bromide hemihydrate, (2.1 g), melting point 199°-200° C.
