Versuchsvorschrift

7.40 g (18 mmoles) of (E)-1-[4-(2-azidoethoxy)-phenyl]-1,2-diphenyl-3,3,3-trifluoro-propene, prepared as described in Example 7, are dissolved in 100 ml of methanol, 0.70 g of a 5% palladium-on-carbon catalyst are added, and the mixture is hydrogenated for about one hour. The catalyst is filtered off, the solution is evaporated, and the residue is crystallized from hexane. 3.63 g (52.3%) of the aimed compound are obtained; m.p.: 71°-76° C.
