Patent ID: 8357689

Claim:
A compound of formula wherein R denotes a group of formula wherein R 1 denotes H, C 1-6 -alkyl-carbonyl-oxy-C 1-3 -alkyl or C 1-6 -alkoxy-carbonyl-oxy-C 1-3 -alkyl, R 2 and R 3 independently of one another denote H, halogen, C 1-3 -alkyl, C 1-3 -perfluoroalkyl, C 1-3 -perfluoroalkoxy, C 1-3 -alkoxy, cyano or nitro and A denotes CH or N, and the heterocyclic group denotes a group of formula wherein the above-mentioned heterocycles of formulae (Ia), (Ic), (Id), (Ie), (Ig) and (Ij) may optionally be substituted at the carbon atoms of the 5 ring in each case by one or two groups selected from among halogen, C 1-3 -alkyl, cyano, C 1-3 -perfluoroalkyl, C 3-6 -cycloalkyl C 2-4 -alkynyl, C 2-4 -alkenyl, C 1-3 -alkyl-carbonyl, C 1-3 -perfluoroalkyl-carbonyl, carboxyl, aminomethyl, C 1-3 -alkyl-aminomethyl, di-(C 1-3 -alkyl)-aminomethyl, aminocarbonyl, C 1-3 -alkyl-aminocarbonyl or di-(C 1-3 -alkyl)-aminocarbonyl, wherein the groups are identical or different and each carbon atom can only carry one group, and wherein R 4 denotes a 1H-pyrimidin-2,4-dionyl or 2H-pyridazin-3-onyl group optionally mono- or disubstituted by one or two methyl groups or an optionally substituted aryl or heteroaryl group, or the tautomers, stereoisomers, mixtures thereof and salts thereof.
