    Abstract: The invention relates to a novel process for producing thereof hydroxyarenes of the general formula (I) in which n represents the numbers 1, 2, 3 or 4, R represents cyano, carboxyl, formyl, nitro, halogen or represents alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl, alkylcarbonyl or alkoxycarbonyl, each of which is optionally substituted, and Z represents hydrogen, cyano, nitro, halogen, alkyl, halogenoalkyl, or represents monocyclic or bicyclic, saturated or unsaturated heterocyclyl, heterocyclylamino or heterocyclylimino, each of which is optionally substituted, characterized in that halogenoarenes of the general formula (II) in which n, R and Z are each as defined above and X represents halogen are reacted with 3-hydroxy-propionitrile of the formula (III), HO—CH2CH2—CN  (III), if appropriate in the presence of a reaction auxiliary and if appropriate in the presence of a diluent, at temperatures between 0° C. and 100° C.

    Abstract: The present invention relates to a novel process for preparing known 1-amino-3-phenyluracil derivatives, to novel 1-amino-6-hydroxy-3-phenyldihydro-2,4(1H,3H)pyrimidinedione derivatives of the formula (II) in which R1 is hydrogen, cyano, nitro or halogen, R2 is cyano, nitro, halogen or optionally substituted alkyl or alkoxy, R3 is hydrogen, hydroxyl, mercapto, amino, hydroxyamino, hydrazino, halogen, or one of the radicals —R6, -Q-R6, —NH—R6, —NH—O—R6, —NH—SO2—R6, —N(SO2—R6)2, —CQ1-R6, —CQ1-Q2-R6, —CQ1-NH—R6, -Q2-CQ1-R6, —NH—CQ1-R6, —N(SO2—R6)(CQ1-R6), -Q2-CQ1-Q2-R6, —NH—CQ1-Q2-R6 or -Q2-CQ1-NH—R6, where Q is O, S, SO or SO2, Q1 and Q2 are each independently oxygen or sulphur and R6 is optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heterocyclylalkyl, R4 is hydrogen, halogen or optionally substituted alkyl, and R5 is fluorine- and/or chlorine-substituted alkyl, as intermediates for the 1-amino-3-phenyluracil derivatives, and to a process for preparing the intermediates.
