    Abstract: In the present invention there is disclosed a derivative of 2-[(2-alkoxy-6-trifluoromethylpyrimidin-4-yl)oxymethylene]phenylacetic acid of the general formula I, in which U represents CH or nitrogen, V represents oxygen or NH, R represents alkyl containing 1 to 6 carbon atoms, Re1 represents CN, a halogen, alkyl containing 1 to 4 carbon atoms, haloalkyl containing 1 to 4 carbon atoms in the alkyl moiety, alkoxy containing 1 to 4 carbon atoms, haloalkoxy containing 1 to 4 carbon atoms in the alkoxy moiety or phenyl, a is 0 or an integer ranging from 1 to 4, whereby the groups Re1 can be different if a is greater than 1. The preparation process is characterized in that pyrimidin-4-ol of the general formula II is brought into reaction in an inert organic solvent and in the presence of a base with a benzyl derivative of the general formula III, wherein X represents nucleophilic exchangeable released group and the other general symbols are as specified above or a sulfone derivative of the general formula IV, wherein Rea represents an alkyl group containing 1 to 4 carbon atoms is brought in the presence of a base into reaction with the alcohol of the general formula V HO-R (V), where the individual general symbols are as specified above. The derivative is suitable for fighting animal pest and harmful fungi.
