Procedure

Benzaldehyde (2-hydroxyethyl)hydrazone is prepared by condensation of benzaldehyde with (2-hydroxyethyl)hydrazine according to the following procedure: 10-2 moles of (2-hydroxyethyl)hydrazine are added to a solution containing 10-2 moles of benzaldehyde in 20 ml of ethanol. The reaction is left under reflux for 30 minutes. The mixture is then cooled. The solvents are removed by evaporation. The product obtained is an extremely unstable oil. The crude reaction yield is 97%.
