33.4 g (0.093 mol) of N-[3-(4-bromophenyl)-prop-2-enyloxy]-phthalimide were introduced a little at a time into 50 ml of ethanolamine; the temperature increased to 30° C. After stirring had been carried out for two hours at 60° C., the mixture was allowed to cool and 200 ml of dichloromethane were added to it. It was extracted by shaking with iced water. The organic phase was dried and evaporated down and the residue was crystallized from petroleum ether. 20.2 g (95.3% of theory) of 3-(4-bromophenyl)-prop-2-enyloxyamine of melting point 35°-38° C. were obtained.
