Novel anthelmintics are described which, as active ingredient, contain a compound of the formula I <IMAGE> (I) or in its hydrogenated form the formula (Ia) <IMAGE> (Ia) in which R1 and R2 independently of one another are C1-C6alkyl, allyl, C3-C6cycloalkyl, benzyl or phenyl; R3 is an unsubstituted or substituted heteroaromatic 6-membered ring which contains 1, 2 or 3 nitrogen atoms or a benzo-fused, unsubstituted or substituted heteroaromatic 6-membered ring which contains 1 to 3 nitrogen atoms, and R4 and R5 independently of one another are hydrogen, C1-C4alkyl, C1-C4alkoxy or halogeno-C1-C3alkyl, including their tautomeric forms and physiologically tolerable salts. The preparation, formulation and use of these active ingredients are also described.
