An updated downstream synthesis route of 873191-23-2 as follows.<\/p>\n<p>General procedure: The phenanthridine skeletons1-8 (0.1 mmol) were dissolved in dryTHF (10 mL), and NaH (50 mg, 2 mmol), and 3-(bromomethyl)pyridine,3-(chloromethyl)-1,5-dimethyl-1H-pyrazole or 5-bromomethyl-1,3-dimethyl-1H-pyrazole (1 mmol) were added. The mixture was stirred atrt. for 12 h and quenched with H2O (50 mL) in an ice bath. The solutionwas evaporated to remove the THF and extracted with CH2Cl2(2\u00d730 mL). The organic layer was washed with saturated NaHCO3 andbrine, dried over MgSO4, filtered and concentrated. The residue waspurified by column chromatography using petroleum-EtOAc as theeluent to afford about 35 mg of each phenanthridine compound.<\/p>\n<p>According to the analysis of related databases, 873191-23-2, the application of this compound in the production field has become more and more popular.<\/p>\n<p>Reference:<br \/><a href=\"https:\/\/doi.org\/10.1016\/j.bioorg.2018.11.020\">Article; Chen, Duo-zhi; Yang, Bi-juan; He, Xiao-li; Fan, Shi-rui; Cai, Jie-yun; Jing, Chen-xu; Zhang, Heng; Zhang, Yu; Li, Lin; Hao, Xiao-jiang; Bioorganic Chemistry; vol. 84; (2019); p. 285 &#8211; 294;<\/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>According to the analysis of related databases, 873191-23-2, the application of this compound in the production field has become more and more popular.<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[621,131],"tags":[126],"class_list":["post-4090","post","type-post","status-publish","format-standard","hentry","category-873191-23-2","category-pyrazoles-derivatives","tag-m-w100-200"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Some tips on<\/title>\n<meta name=\"description\" content=\"Reference of 873191-23-2, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.
