摘要:
The invention concerns a novel method for the production of 1-amino-3-aryl-uracil of formula (I), wherein R1 represents optionally substituted alkyl; R2 represents hydrogen, nitro, cyano, halogen or optionally substituted alkyl; R3 represents hydrogen, nitro, cyano or halogen; R4 represents hydrogen, nitro, cyano, carbamoyl, thiocarbamoyl, hydroxy, halogen or optionally substituted alkyl, alkoxy or benzoyloxy and R5 represents hydrogen, hydroxy, mercapto, amino, hydroxyamino, nitro, cyano, carboxy, carbamoyl, Thiocarbamoyl, halogen or one of the following groupings: -R?6, -Q-R6, -NH-R6¿, -NH-O-R6, -NH-SO¿2?-R6, -N(SO2R?6)¿2, -CQ?1-R7, -CQ1-Q2-R6, -CQ1-NH-R6, -Q2-CQ1-R6, -Q2-CQ1-Q2-R6¿, -NH-CQ?1-R6, -N(SO2-R6)-(CQ1-R6¿), -NH-CQ?1-Q2-R6, -Q2-CQ1-NH-R6¿, wherein Q represents O, S, SO or SO¿2?, Q?1 and Q2¿ independently represent O or S and R represents optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heterocyclylalkyl.
