wherein:
R1 is selected from (C1-C6)-alkyl, where one or more hydrogens in the alkyl radical may be replaced by fluorine; phenyl, (C1-C8)-alkylene-phenyl, heterocyclyl, (C1-C8)-alkylene-heterocyclyl, where the phenyl or heterocycle radical may be substituted one or more times by a substituent selected from F, Cl, Br, NO2, COO—(C1-C6)-alkyl, (C1-C6)-alkylene-O—(C1-C6)-alkyl, OCF3, (C1-C6)-alkyl, CO—(C1-C6)-alkyl, phenyl, SCF3, and SF5;
and the heterocycle is selected from the group consisting of thiophene, quinoline, oxadiazole, isoxazole and pyridine and may be fused to a benzene ring;
R2 is selected from phenyl and heterocycle, where the phenyl or heterocycle radical may be substituted one or more times by a substituent selected from F, Cl, Br, NO2, COO—(C1-C6)-alkyl, (C1-C6)-alkylene-O—(C1-C6)-alkyl, OCF3, (C1-C6)-alkyl, CO—(C1-C6)-alkyl, phenyl, SCF3, and SF5 and the heterocycle is selected from the group consisting of dioxole, tetrahydrofuran, isoxazole, oxazine, thiophene and pyridine and may be fused to a benzene ring; and
R3 and R4 are, independently of one another, selected from H, F, Cl, Br, NO2, COO—(C1-C6)-alkyl, (C1-C6)-alkylene-O—(C1-C6)-alkyl, OCF3, (C1-C6)-alkyl, CO—(C1-C6)-alkyl, phenyl, SCF3, and SF5;
where the compound of the following formula is excluded
