FIELD: chemistry.
SUBSTANCE: in formula (I) R1 is 1-propynyl, phenyl or 6-membered heteroaryl, which contains one or two nitrogen heteroatoms, wherein said heteroaryl is optionally substituted with one or two substituents R15; R2 is ethyl or chlorine; R3 is selected from the group consisting of methyl, ethyl, methoxy and chlorine; R4 is selected from a group consisting of -C(=O)C1-C4alkyl, -C(=O)C1-C4haloalkyl, -S(O)nC1-C6alkyl, -C(O)-(CH2)n-C3-C6cycloalkyl, -C(O)(CR9R10)CN, -C(O)C1-C3alkoxyC1-C6alkyl, -C(O)C1-C3alkoxyC2-C6alkenyl, -C(O)C1-C3alkoxyC1-C6haloalkyl , -C(O)(CH2)nNR5R6, -C(O)-(CH2)n-NR7C(O)R8, -C(O)C(O)R20, -C(O)-(CH2)n-phenyl and -C(O)-(CH2)n-heterocyclyl, where each heterocyclyl is 5- or 6-membered heterocyclyl, which can be aromatic, saturated or partially saturated and can contain from 1 to 4 heteroatoms, each of which is independently selected from the group consisting of oxygen, nitrogen and sulphur, and wherein said heterocyclyl or phenyl groups are optionally substituted with one, two or three substituents independently selected from the group consisting of C1-C3alkyl, C1-C3haloalkyl, C1-C3alkoxy and halogen; R5 is independently selected from a group consisting of hydrogen and C1-C6alkyl; R6 is selected from the group consisting of hydrogen and C1-C6alkyl; R7 is hydrogen; R8 is selected from the group consisting of C1-C6alkyl and pyridyl; R9 is hydrogen; R10 is hydrogen; R15 is independently selected from the group consisting of cyano and halogen; R20 is -NR21R22; R21 is hydrogen; R22 is hydrogen; G is hydrogen; n independently equals 0, 1 or 2. Invention also relates to a herbicidal composition containing said compound and a method of controlling weeds in a growing area using said composition.
EFFECT: invention relates to a compound of formula (I), which can be used in agriculture as an herbicide.
