FIELD: organic chemistry. SUBSTANCE: product: triazole derivative of the general formula (I): where R1 - lower alkyl; R2 and R3 - halogen independently; X - chlorine at 2- or 6-position. Invention proposes an aphicide agent based on triazole derivative of the general formula (I) and methods of synthesis of triazole derivative of the general formula (I) by means of: a) interaction of compound of the general formula (II):
with hydrazine R1-NHNH2 or b) interaction of compound of the general formula (III)
with benzonitrile derivative of the formula:
in the presence of Lewis acid, or c) interaction of compound of the general formula (IV)
with compound of the formula:
. The synthesized compounds were used in agriculture. EFFECT: improved method of synthesis. 7 cl, 5 tbl
