Versuchsvorschrift
To a solution of ethyl 2-(3-bromo-2,4,5-trifluorobenzoyl)-3-ethoxyacrylate (1.75 g) in absolute ethanol (5 ml) was added a solution of cyclopropylamine (0.32 g) in absolute ethanol (2 ml) under ice-cooling during 30 minutes. The mixture was stirred at 5°-20° C. for 2.5 hours and concentrated. The residue was recrystallized from petroleum ether to give the title compound (1.36 g), mp 74°-76° C.
