실험 절차

100 mg (0.39 mmol) of (Z)-4-ethoxy-2-[(4-methylphenyl)imino]cyclohex-3-en-1-ylidene methanol are dissolved in 10 ml of anhydrous tetrahydrofuran, and 325 μl (2.3 mmol) of triethylamine and 60 μl (0.78 mmol) of methanesulphonyl chloride are added at 0° C. After 30 min of stirring at 25° C., the mixture is once more cooled to 0° C., 40 μl (0.35 mmol) of 2,4-difluorobenzenethiol are added and the mixture is stirred at 25° C. for a further 30 min. The reaction mixture is diluted with water and extracted with ethyl acetate, and the organic phase is washed with saturated aqueous sodium chloride solution and dried over sodium sulphate. Purification of the residue by column chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate) gives 41 mg of N-(6-{[(2,4-difluorophenyl)sulphanyl]methylene}-3-ethoxycyclohex-2-en-1-ylidene)-4-methylaniline as an isomer mixture (ratio about 1:1).
