실험 절차

5.37 g (12 mmoles) of (E)-1-[4-(2-bromoethoxy)-phenyl]-1,2-diphenyl-3,3,3-trifluoro-propene, prepared as described in Example 7, are boiled with 8.8 g of diethylamino for 5 hours. The reaction mixture is diluted with 50 ml of benzene, washed with water until neutral, dried and evaporated. The residue is dissolved in 20 ml of 95% ethanol, and a solution of 3.22 g (14 mmoles) of picric acid in 32 ml of 95% ethanol is added. The separated crystals are filtered off, washed with ethanol and ether. 6.46 g (80.4%) of the aimed compound are obtained; m.p.: 131°-135° C.
