Versuchsvorschrift

192 g (1mole) of 3,4-dichloro-nitrobenzene is added to 810 cm3 (10 moles) ethylene diamine hydrate. The reaction mixture is heated at reflux for 4 hours and then poured into 2.5 liters of ice water. Drying yields 205 g of 4-nitro-2-chloro-N-(β-aminoethyl) aniline which, after recrystallization in absolute ethanol, melts at 116° C.
