    摘要: The present invention relates to a novel process for preparing known 1-amino-3-phenyluracil derivatives (1-amino-3-phenyl-2,4(1H,3H)pyrimidinedione derivatives) and novel 1-amino-6-hydroxy-3-phenyldihydro-2,4(1H,3H)pyrimidinedione derivatives of the formula (II) 1 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 nullR6, -Q-R6, nullNHnullR6, nullNHnullOnullR6, nullNHnullSO2nullR6, nullN(SO2nullR6)2, nullCQ1-R6, nullCQ1-Q2-R6, nullCQ1-NHnullR6, -Q2-CQ1-R6, nullNHnullCQ1-R6, N(SO2nullR6)(CQ1-R6), -Q2-CQ1-Q2-R6, nullNHnullCQ1-Q2-R6 or -Q2-CQ1-NHnullR6, where Q is O, S, SO or SO2, Q1 and Q2 are each independently oxygen or sulphur and R6 is optionally substituted alkyl, alkenyl, alkinyl, 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 therefor and to a process for preparing them.

    摘要: The invention relates to a process for obtaining L-dihydroorotic acid by chromatography on an anionic exchange material in a base water mixture under a pressure from about 1.1 MPa to about 40 MPa. The process can be used to investigate the in vitro and in vivo activity of N-(4-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide, N-(4-trifluoromethylphenyl)-2-cyano-3-hydroxycrontonamide and similar compounds.
