DERIVATIVES OF SUBSTITUTED QUINOLINES AND METHOD OF SYNTHESIS OF 3-METHOXYMETHYL-7- OR 8-HYDROXYQUINOLINE

摘要

FIELD: organic chemistry. SUBSTANCE: invention relates to new substituted intermediate quinoline compounds used for synthesis of a herbicide, namely, 2-(4-isopropyl-4-methyl-5-oxo-2-imidazo-lidinyl)-5-methoxymethylnicotinic acid and to a method of synthesis of an intermediate compound, for example, 3-methoxymethyl-7- or 8-hydroxyquinoline which can be used for synthesis of the indicated herbicide. Invention describes the compound of the formula (I) where X means direct or branched C₁-C₆-alkyl, phenyl, direct or branched -O-(C₁-C₄)-alkyl, where Y and Z mean independently H, direct or branched (C₁-C₆)-alkyl or phenyl and B means H, chlorine or bromine atom or quaternary base halide. EFFECT: simplified method of synthesis. 10 cl, 18 ex
