Patent ID: 6936609

Claim:
A compound of general formula (I), in which R 1 represents (C 6 -C 10 )-aryl, which is optionally identically or differently substituted by radicals selected from the group consisting of halogen, formyl, carbamoyl, cyano, hydroxyl, trifluoromethyl, trifluoromethoxy, nitro, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy, and optionally by a radical of the formula —SO 2 NR 5 R 6 , in which R 5 and R 6 independently of one another denote hydrogen or (C 1 -C 6 )-alkyl, or NR 5 R 6 denotes 4- to 8-membered heterocyclyl, bonded via a nitrogen atom, optionally identically or differently substituted by radicals selected from the group consisting of oxo, halogen, (C 1 -C 6 )-alkyl and (C 1 -C 6 )-acyl, R 2 represents a saturated or partially unsaturated hydrocarbon radical having 1 to 10 carbon atoms, R 3 represents methyl or ethyl, A represents O, S or NR 7 , in which R 7 denotes hydrogen or (C 1 -C 6 )-alkyl optionally substituted by (C 1 -C 3 )-alkoxy, E represents a bond or (C 1 -C 3 )-alkanediyl, R 4 represents (C 6 -C 10 )-aryl or 5- to 10-membered heteroaryl, where aryl and heteroaryl are optionally identically or differently substituted by radicals selected from the group consisting of halogen, formyl, carboxyl, carbamoyl, —SO 3 H, aminosulphonyl, cyano, hydroxyl, trifluoromethyl, trifluoromethoxy, nitro, (C 1 -C 6 )-alkyl, (C 1 -C 6 )-alkoxy, 1,3-dioxa-propane-1,3-diyl, (C 1 -C 6 )-alkylthio, (C 1 -C 6 )-alkylsulphinyl and (C 1 -C 6 )-alkyl-sulphonyl, —NR 8 R 9 end optionally methyl-substituted, 5- to 6-membered heteroaryl or phenyl, in which R 8 and R 9 independently of one another denote hydrogen, (C 1 -C 6 )-alkyl or (C 1 -C 6 )-acyl, or salt thereof.
