FIELD: organic chemistry, chemical technology, fungicides.
SUBSTANCE: invention describes derivative of benzoylpyridine of the formula (I) or its salt:
wherein X represents halogen atom, (C1-C6)-alkoxy-group optionally substituted with a substitute taken among halogen atom, phenyl, methoxy-, methylthio-, dimethylamino-group, vinyl or ethynyl; phenoxy-group, (C3-C6)-cycloalkoxy-group, hydroxyl group, (C1-C6)-alkyl group, (C2-C6)-alkenyl group, CF3, (C1-C6)-alkylthio-group, (C1-C6)-alkoxycarbonyl group, (C1-C6)-dialkylaminocarbonyl group, (C1-C6)-alkylcarbonyloxy-group, (C1-C6)-alkylcarbonyl group, amino-group, (C1-C4)-alkylamino-group or di-(C1-C4)-alkylamino-group; n represents 1, 2, 3 or 4; R1 represents (C1-C6)-alkyl group; R2 represents (C1-C6)-alkyl group, (C1-C6)-alkoxy-group optionally substituted with phenyl, phenoxy-group, (C3-C10)-cycloalkyloxy-group or hydroxyl group; m = 1, 2 or 3 under condition that if m = 2 then R2 can form ring -OCH2O- (with exception when pyridine ring is substituted with benzoyl group at 2-position; pyridine ring is substituted with (C1-C6)-alkoxy-group, hydroxyl group or benzyloxy-group; n = 1; m = 1 or 2). Also, invention describes fungicide comprising compound of the formula (I) or it salt as an active component, methods for preparing derivatives of benzoylpyridine, phenylpyridylmethanol that is an intermediate compounds used for synthesis of compound of the formula (I). Invention provides fungicide properties of compound of the formula (I) or its salt.
EFFECT: improved method for preparing, valuable properties of compounds.
