Patent ID: 8440700

Claim:
A compound of the formula (I) in which A represents O or S, R 1 represents hydrogen or (C 1 -C 4 )-alkyl, R 2 represents hydrogen or (C 1 -C 4 )-alkyl which may be substituted by hydroxyl, (C 1 -C 4 )-alkoxy or up to three times by fluorine or R 1 and R 2 are attached to one another and together with the carbon atom to which they are attached form a cyclopropane or cyclobutane ring, R 3 represents hydrogen, halogen or (C 1 -C 4 )-alkyl, R 4 and R 5 are identical or different and independently of one another represent hydrogen or (C 1 -C 6 )-alkyl which may be mono- or disubstituted by identical or different substituents from the group consisting of hydroxyl, (C 1 -C 4 )-alkoxy, amino, mono-(C 1 -C 4 )-alkylamino, di-(C 1 -C 4 )-alkylamino, carboxyl, and (C 1 -C 4 )-alkoxycarbonyl; and either (i) R 6 represents (C 6 -C 10 )-aryl which may be mono- to trisubstituted by identical or different substituents from the group consisting of halogen, nitro, cyano, (C 1 -C 4 )-alkyl, trifluoromethyl, hydroxyl, (C 1 -C 4 )-alkoxy, difluoromethoxy, trifluoromethoxy, mono-(C 1 -C 4 )-alkylaminocarbonyl, (C 1 -C 4 )-alkoxycarbonyl and carboxyl, and R 7 represents hydrogen, fluorine, chlorine, (C 1 -C 4 )-alkyl, trifluoromethyl, (C 1 -C 4 )-alkoxycarbonyl, carboxyl or phenyl, where the (C 1 -C 4 )-alkyl may be substituted by hydroxyl or (C 1 -C 4 )-alkoxy and the phenyl may be substituted by halogen, cyano, (C 1 -C 4 )-alkyl or trifluoromethyl, or (ii) R 6 represents hydrogen or (C 1 -C 4 )-alkyl and R 7 represents phenyl which may be mono- or disubstituted by identical or different substituents from the group consisting of halogen, cyano, (C 1 -C 4 )-alkyl and trifluoromethyl, or a salt thereof.
