The reaction was heated to 35 C for 30 minutes and then treated with a dimethylformamide (&#8220;DMF&#8221;) solution (24 mL) of 4-bromo-2-fluoropyridine (10.3 g, 58.5 mmol). The reaction was heated to 50 C and stirred for 1 hour. The reaction was allowed to cool and treated with water, and the organics were concentrated. The residue was diluted with ethyl acetate and washed with water and brine. The organics were dried over Na2S04, filtered and concentrated. The material was purified on silica gel eluting with 30-100% ethyl acetate\/hexanes followed by 25% methanoLDCM to afford 4-bromo-N-(l-methyl-lH-pyrazol-5-yl)pyridin-2-amine (6.55 g, 25.9 mmol, 44.2% yield).<\/p>\n<p>The synthetic route of 1192-21-8 has been constantly updated, and we look forward to future research findings.<\/p>\n<p>Reference:<br \/><a href=\"http:\/\/v3.espacenet.com\/textdoc?DB=EPODOC&#038;IDX=WO2015103137&#038;F=0\">Patent; ARRAY BIOPHARMA INC.; GENENTECH, INC.; BLAKE, James, F.; COOK, Adam; GAUDINO, John; GUNAWARDANA, Indrani, W.; HICKEN, Erik, James; HUNT, Kevin, W.; LYON, Michael; METCALF, Andrew, T.; MOHR, Peter, J.; MORENO, David, A.; NEWHOUSE, Brad; REN, Li; SCHWARZ, Jacob; CHEN, Huifen; GAZZARD, Lewis; SCHMIDT, Jane; DO, Steve; WO2015\/103137; (2015); A1;<\/a>,<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<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The synthetic route of 1192-21-8 has been constantly updated, and we look forward to future research findings.<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[191,131],"tags":[145],"class_list":["post-5292","post","type-post","status-publish","format-standard","hentry","category-1192-21-8","category-pyrazoles-derivatives","tag-m-w0-100"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Research on new synthetic routes about<\/title>\n<meta name=\"description\" content=\"In the next few decades, the world population will flourish.
