And the patent contained the following:<\/p>\n<p>The invention relates to amides and thioamides of formula I, to a method for the production thereof, and to the use thereof for combating pests. Compounds of formula I wherein G is N, CH, C-halo, C-NO2, C-CN, etc.; R1 is H, alkyl, haloalkyl, cycloalkyl, halo, etc.; X is O and S; R2 is H, alkyl, haloalkyl, alkoxy, etc.; R3 is H, alkyl, haloalkyl, cyanoalkyl, alkenyl, etc.; and their salts and N-oxides thereof, are claimed. Example compound II was prepared by N-arylation of pyrazole-4-carbonitrile with 3-bromopyridine; the resulting 1-(pyridin-3-yl)-1H-pyrazole-4-carbonitrile underwent hydrolysis to give the corresponding carboxylic acid, which underwent chlorination to give the corresponding carboxylic acid chloride hydrochloride, which underwent amidation with ethylamine to give compound II. All the invention compounds were evaluated for their pesticidal activity (some data given). The experimental process involved the reaction of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid(cas: 1014631-89-0).<a href=\"https:\/\/www.ambeed.com\/products\/1014631-89-0.html\">Reference of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid<\/a><\/p>\n<p>The Article related to amide thioamide preparation pesticide, Heterocyclic Compounds (More Than One Hetero Atom): Pyrazoles and other aspects.<a href=\"https:\/\/www.ambeed.com\/products\/1014631-89-0.html\">Reference of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid<\/a><\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">Pyrazole &#8211; Wikipedia<\/a>,<br \/><a href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/pyrazoles\">Pyrazoles &#8211; an overview | ScienceDirect Topics<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Article related to amide thioamide preparation pesticide, Heterocyclic Compounds (More Than One Hetero Atom): Pyrazoles and other aspects.<a href=\"https:\/\/www.ambeed.com\/products\/1014631-89-0.html\">Reference of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid<\/a><\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[768,131],"tags":[128],"class_list":["post-10897","post","type-post","status-publish","format-standard","hentry","category-1014631-89-0","category-pyrazoles-derivatives","tag-100-200"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Bretschneider, Thomas et al. published their patent in 2011 |CAS: 1014631-89-0 | pyrazoles-derivatives<\/title>\n<meta name=\"description\" content=\"On April 21, 2011, Bretschneider, Thomas; Voerste, Arnd; Fuesslein, Martin; Koehler, Adeline; Goergens, Ulrich published a patent.Reference of 1-(Pyridin-3-yl)-1H-pyrazole-4-carboxylic acid The title of the patent was Amides and thioamides as pesticides and their preparation.
