FIELD: agriculture. SUBSTANCE: desired products represent amides of unsaturated acids or their salt. Said amides have formula Q1QCR2=CR3CR4=CR5C(X)NHR′ where Q is phenyl, naphthyl, pyridyl, dihalovinyl, each of them may be substituted by 1-3 substituents which are chosen of C1-C6 alkyl, C1-C6 alkoxy, CF3 and halogen. Q′ is 1,2-cyclopropyl optionally substituted by C1-C4 alkyl or by halogen R2, R3, R4 and R5 being the same or different represent hydrogen, halogen, C1-C6 alkyl, haloCl-C4 alkyl, one of said radical being certainly hydrogen, R1 is hydrogen, C1-C6 alkyl which may be substituted by dioxalyl group, cycloC3-C6 alkyl, 2-methyl-2-propenyl, X is O, S. Compound having formula QQ′CR2=CR3CR4Z, where Z is O or CR5C(X)Z′ is used as reagent 1, amine being used as reagent 2. Reaction is carried out at (-25 C)-(+150 C) in anhydrous aprotic solvent. EFFECT: improves quality of desired product. 7 cl, 11 tbl
