実験手順
4 g of 2-[(1H-indol-4-yl)-ethenyl]-phenol obtained in Step A of Example 1 in 100 ml of 2N sodium hydroxide after having added 6 g of 2-chloroethanol tosylate were heated for 6 hours at reflux and the mixture was left for 16 hours at ambient temperature, then diluted with water and extracted with ethyl acetate. After eliminating the solvent under reduced pressure and chromatography on silica (eluent: benzene), 2 g of 4-[2-[2-[(2-chloro)-ethoxy]-phenyl]-ethenyl]-1H-indole (trans E) were obtained.
