Reaction Steps
add 1.75 g of iron powder to a solution of 1.4 g of 4-[(2,6-dichlorobenzyl)oxy]-2-nitroaniline in 80 cm3 of methanol and 7 cm3 of glacial acetic acid. The reaction mixture is refluxed for three hours. The mixture is concentrated under reduced pressure (0.2 kPa). The residue is taken up in 30 cm3 of water and the pH of the suspension thus obtained is adjusted to 10-11 by adding 2N aqueous solution of sodium hydroxide; 350 cm3 of dichloromethane is then added. After vigorous stirring for 15 min, the insoluble matter is filtered. The filtrate is decanted, then the organic phase is dried over magnesium sulphate, filtered and concentrated under reduced pressure (0.2 kPa). We obtain 1.11 g of 4-[(2,6-dichlorobenzyl)oxy]benzene-1,2-diamine in the form of a black resin, which has the following characteristics:
