Procedure

2-Phenyl-3,3,3-trifluoro-1-(4-fluorophenyl)-1-(4-methoxyphenyl)-propane, prepared as described in Example 18, is reacted with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone under boiling for 8 hours as described in Example 7. The reaction mixture is processed, and the product is crystallized from ethanol. 2-Phenyl-3,3,3-trifluoro-1-(4-fluorophenyl)-1-(4-methoxyphenyl)-propene is obtained with a yield of 51%; m.p.: 52°-56° C.
