실험 절차

2-Picoline (9.3 g, 0.1 mole) and benzyl bromide (17.1 g, 0.1 mole) were refluxed in isopropanol (50 ml) overnight. The solvent was evaporated giving an oil which was heated at 100° C. for six hours. The resulting crude oil (8.5 g, 0.032 mole) and 4-diethylaminobenzaldehyde (6.0 g, 0.033 mole) were refluxed in methanol (40 ml) in the presence of piperidine (0.2 ml) under nitrogen for three hours. On cooling dark-coloured crystals were obtained which were collected to give 1-benzyl-2-[4-(diethylamino)styryl]pyridinium bromide (6.2 g), melting point 231°-233° C.
