Procedure

2.0 g (4.2 mmol) of 3-(4-bromo-5-ethylsulfonylamino-2-fluorophenyl)-1-methyl-6-trifluoromethyl-2,4(1H,3H)pyrimidinedione, 0.3 g of zinc cyanide and 0.5 g of tetrakis(triphenylphosphine)palladium were added to 10 g of 5-ethyl-2-picoline and the mixture was stirred at 80° C. under an argon atmosphere for 3.5 hours. After the reaction was completed, 94% of the title compound was detected as the relative area value in liquid chromatography.
