[Figure not available: see fulltext.] A novel compound, 3,7-dichloro-N-(2,6-diethylphenyl)-N-(2-propoxyethyl)quinoline-8-carboxamide was synthesized by splicing together a chloro-substituted quinoline moiety found in quinclorac (a selective herbicide) and a substituted amide moiety found in pretilachlor (another selective herbicide) using the active substructure splicing method. The chemical structure of this compound was characterized by 1H, 13C NMR, FTIR, high-resolution mass spectra and X-ray diffraction analysis. Pesticide potency (herbicidal and fungicidal activity) of this compound was evaluated. This compound displayed excellent control efficiency against Echinochloa crusgalli and also showed good fungicidal in vitro activity against Phytophthora capsici, Phytophthora sojae, and Phytophthora infestans.

The invention discloses a pretilachlor synthesis method. The pretilachlor synthesis method comprises steps as follows: sodium propanolate is dissolved in an organic solvent I, 2-chloroacetaldehyde dimethyl acetal is added dropwise, and heat is preserved until the reaction is performed completely; propoxy acetaldehyde dimethyl acetal and tetrahydrofuran are mixed, aqueous acid is added, and heat is preserved until the reaction is performed completely; 3-propoxy propionaldehyde, 2,6-diethyl aniline and an organic solvent II are mixed, a catalyst is added, hydrogen is introduced until certain pressure is obtained, and heat is preserved until the reaction is performed completely; amidogen ether, a sodium hydroxide solution and methylbenzene are mixed, chloroacetyl chloride is added dropwise at certain temperature, heat is preserved until the reaction is performed completely, and pretilachlor is prepared. With the adoption of the method, high-quality pretilachlor can be obtained.
