Reaction Steps

77.2 g of E-1-bromo-2-(4-fluorophenyl)-3-(2-chlorophenyl)-prop-2-ene are heated at 180° C. for one hour. The reaction mixture is cooled to room temperature and 200 ml of ethanol are added. Thereafter, 10 g of active carbon are added and the mixture is heated to 50° C. and filtered while hot. 26.9 g (35%) of Z-1-bromo-2-(4-fluorophenyl)-3-(2-chlorophenyl)-prop-2-ene of melting point 73°-75° C. are obtained from ethanol.
