실험 절차

4-Nitrophenoxy sodium dihydrate (29.39 g), 2-(diethylamino)ethylchloride hydrochloride (25.60 g), potassium carbonate (30.17 g) and water (60 ml) were added into xylene (100 ml) and the mixture was heat-refluxed for 2 hours while mixing and continuously removing water by azeotropic distillation. After reaction, insolubles were removed by filtration. Filtrate was added with ethyl acetate (100 ml) and extracted 3 times with 1N HCl (100 ml). Aqueous layer was adjusted to pH 10 with 1N sodium hydroxide and oily substance separated was extracted 3 times with ethyl acetate (100 ml). Ethyl acetate solution was dehydrated with anhydrous magnesium sulfate and concentrated to obtain N,N-diethyl-2-(4-nitrophenoxy)ethylamine (28.19 g) as color-less oily substance.
