Participants

Reaction Steps

26.1 g (0.30 mol) of morpholine 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. After cooling the majority of the solvent was removed in a rotary evaporator. 250 ml of distilled water were added to the residue. After a certain time, a solid began to precipitate out, which was filtered out and dried.
