Participants

Reaction Steps

25.5 g (0.30 mol) of piperidine were added to 24.0 g (0.30 mol) of a 37% aqueous formaldehyde solution in 180 ml of ethanol. Then 30.4 g (0.20 mol) of 4-hydroxy-3-methoxybenzaldehyde (vanillin) were added. The reaction mixture was refluxed for one hour. A solid began to precipitate out as early as during cooling, which was filtered out after complete cooling of the reaction batch and dried.
