反応手順
1-Dodecyl-2-methylpyridinium bromide (2.3 g, 0.0067 mole) and 4-piperidinobenzaldehyde (1.27 g, 0.0067 mole) were refluxed in methanol (20 ml) in the presence of piperdine (0.1 ml) under nitrogen for three hours. The solution was cooled and addition of ether gave a crystalline solid which was collected giving 1-dodecyl-2-[(4-piperidino)styryl]pyridinium bromide (0.85 g), melting point 203°-205° C.
