Reaction Steps

The mixture of powdered zinc (30 g), ammonium chloride (3 g), water (5 ml) and absolute ethanol were brought to reflux with the oil bath. The 4-nitro-N-(3-{[(4-nitrophenyl)amino]methyl}benzyl)aniline (3 g) was dissolved in 50 ml of NMP and introduced dropwise until there was decoloration of the reaction medium, while at the same time the reflux was maintained.
