Abstract

Compounds of the formula I <IMAGE> are prepared by reacting compounds of the formula II <IMAGE> with compounds of the formula III <IMAGE> and then subjecting the compound obtained to a ring closure reaction, R<1> denoting lower alkyl, R<2> denoting lower alkyl or aralkyl and R<3> denoting hydrogen or lower acyl. The compounds of the formula I have coccidiostatic action. Ethyl 6-acetoxy-7-ethoxy-4-hydroxyquinoline-3-carboxylate and ethyl 6-hydroxy-7-ethoxy-4-hydroxyquinoline-3-carboxylate have a good action.
