| Product | 1,2-Ethanediamine, N1,N2-bis(phenylmethylene)- | HCID 66033 | — |
Reaction Steps
A mixture of ethylene diamine (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.
