Reaction Steps

34.7 g (0.2 mole) of 4-chloro-3-nitrophenol, 21 g of sodium carbonate, 0.1 g of copper-I chloride and 20 g of n-propylamine are heated in a bath from room temperature up to a bath temperature of 120° C. After 5 hours, the reaction mixture is taken up in water, acidified (pH 2) with hydrochloric acid and extracted 3 times with ethyl acetate in order to remove unreacted starting material. After neutralisation, the aqueous phase is again extracted 3 times with ethyl acetate. After drying and concentration, these extracts give the desired product in the form of a red oil.
