Versuchsvorschrift
42,3 g of (Z)-1,2-diphenyl-1-[4-(2-bromoethoxy)phenyl]-1-buten-4-ol is stirred kith 500 ml of 33% methylamine in ethanol for 10 h at 100° C. in autoclave. The solvent is evaporated and the evaporation residue is dissolved in ethyl acetate in the presence of 2M sodium carbonate solution. After washing the ethyl acetate layer kith water and drying kithsodium sulfate the solvent is evaporated. Recrystallization from toluene gives 27,2 g (73%) of the product having m.p. 135°-9° C.
