Reaktionsschritte
A solution of 1,1-bis(4-chlorophenylsulphonyl)-2-ethoxyethene (1.26 g) and 2-(trifluoromethyl)aniline (0.48 g) in dimethylacetamide (20 ml) was heated at reflux for 2 hours, and then it was cooled and poured onto ice (50 g). The resulting white precipitate was filtered off, washed with water and recrystallised from ethanol, to give 1,1-bis(4-chlorophenylsulphonyl)-2-[2-(trifluoromethyl)anilino]ethene (0.8 g), m.p. 169°-171° C.
