Versuchsvorschrift

1.2 g (2.5 mmol) of 3-(4-bromo-5-ethylsulfonylamino-2-fluorophenyl)-1-methyl-6-trifluoromethyl-2,4(1H,3H)pyrimidinedione and 0.11 g of 55% sodium hydride in oil were added to 20 g of 5-ethyl-2-picoline and the mixture was stirred at room temperature for 30 minutes. Next, 0.07 g of copper(II) chloride and 0.15 g of sodium cyanide were added to the mixture, which was then stirred at 140° C. under an argon atmosphere for 1 hour. Further, 0.3 g of tetrakis(triphenylphosphine)palladium was added to the mixture, which was then heated with stirring for 3 hours. After the reaction was completed, 79% of the title compound was detected as the relative area value in liquid chromatography.
