Reaction Steps

A mixture of 5.0 mL of 2-hydroxy-benzaldehyde, 6.3 mL of benzylamine and 0.05 g of p-toluenesulphonic acid was refluxed in toluene for 2 hours using a Dean-Stark trap to remove liberated water. The volatiles were removed in vacuo yielding 10.1 g of crude 2-(benzylimino-methyl)-phenol.
