On October 20, 2011, Bretschneider, Thomas; Koehler, Adeline; Fischer, Reiner; Fuesslein, Martin; Jescke, Peter; Kluth, Joachim; Muehlthau, Friedrich August; Voerste, Arnd; Malsam, Olga; Goergens, Ulrich; Sato, Yoshitaka published a patent.Recommanded Product: 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid The title of the patent was Preparation of novel heterocyclic compounds as pest control agents. And the patent contained the following:
The invention relates to amides and thioamides of formula I, to a method for the producing same, and to the use thereof for treating animal pests. Compounds of formula I wherein A1 and A2 are independently H, halo, CN, NO2, alkyl, cycloalkyl and alkoxy; G1 is N and CA1; G2 is substituted thiazolyl, thiadiazolyl, and pyrazolyl; are claimed. Example compound II was prepared by reduction of 3-(4-methyl-5-nitrothiazol)pyridine; the resulting 4-methyl-2-(pyridin-3-yl)thiazol-5-amine underwent acylation with 3,3,3-trifluoropropanoyl chloride to give compound II. All the invention compounds were evaluated for their pesticidal activity (data given). The experimental process involved the reaction of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid(cas: 1014631-89-0).Recommanded Product: 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid
The Article related to heterocycle preparation pesticide, Heterocyclic Compounds (More Than One Hetero Atom): Thiazoles, Isothiazoles and other aspects.Recommanded Product: 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid
