Participants

Reaction Steps

A mixture of ethylenediamine (12.02 g; 0.2 mole) and benzaldehyde (42.44 g; 0.4 mole) in toluene (200 ml) was refluxed for 4 hours using a Dean-Stark trap. The toluene was then removed under vacuum. The residual oil crystallized on cooling. The resulting product was dried in a vacuum oven for 24 hours at room temperature and had a melting point of 52°-54° C.
