18.5 g (0.11 mol) of N-hydroxyphthalimide and 31.4 g (0.11 mol) of 1-bromo-[3-(4-bromophenyl)]-prop-2-ene were added in succession to 350 ml of dry N-methylpyrrolidone, and 12.1 g (0.12 mol) of triethylamine were then added dropwise at room temperature. After stirring had been carried out for four days at 20° C., the reaction mixture was poured onto 1.5 1 of ice water and the solid was filtered off and washed with water and isopropanol. 34.3 g (86.8% of theory) of N-[3-(4-bromophenyl)-prop-2-enyloxy]-phthalimide with a melting point of 161°-162° C. were obtained.
