Patent number: 6562833
Abstract: 2-(N-phenylamino)pyrimidines of the formula I,
where:
R1, R3 independently of one another are cyano, C1-C8-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, where the radicals alkyl, alkenyl and alkynyl may be substituted by cyano, halogen, C1-C4-alkoxy or C1-C4-alkoxycarbonyl, or are C3-C8-cycloalkyl or a group C(═NORx)Ry
R2 is halogen, C1-C8-alkyl, C2-C6-alkenyl, C2-C6-alkynyl, where the radicals alkyl, alkenyl and alkynyl may be substituted by cyano, halogen, C1-C4-alkoxy or C1-C4-alkoxycarbonyl, or
R1 and R2 together with the two linking carbon atoms form a fused-on partially unsaturated 4- to 8-membered ring which may be up to trisubstituted by identical or different substituents selected from the group consisting of C1-C4-alkyl, halogen and C1-C4-alkoxy-carbonyl, which may contain a carbonyl group and/or, in addition to the multiple bond of the pyrimidine ring, a double bond and/or which may be interrupted by O, S or N—(C1-C4-alkyl);
the substituents R4 to R8, Rx, Ry, Ra and Rb are
