In 40 mL of absolute ethanol was dissolved 400 mg of bis(2-hydroxybenzyl)-4-(p-nitrobenzyl)-diethylenetriamine (prepared in Example 1) and 100 mg of palladium or activated charcoal (10% Pd). The mixture was hydrogenated at 40 psi (275.8 kPa) for 24 hours. The catalyst was removed by filtration. The ethanolic solution was evaporated to provide bis(2-hydroxybenzyl)-4-(p-aminobenzyl)diethylenetriamine, and was characterized by:
