Application of 92992-85-3, Adding some certain compound to certain chemical reactions, such as: 92992-85-3, name is 2-Bromo-3,5-dimethylpyridine,molecular formula is C7H8BrN, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 92992-85-3.
To a mixture of 2-methylpiperazine-1-carboxylic acid tert-butyl ester (2 g),2-bromo-3,5-dimethylpyridine (1.95 g),tris(dibenzylideneacetone)dipalladium(0)(183 mg),rac-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (250 mg) and tert-butoxy sodium (1.3 g) was added toluene (33 mL) and the mixture was stirred with heating under reflux for 8 hr. The reaction mixture was cooled and filtered through celite. The filtrate was evaporated and the obtained residue was purified by column chromatography (hexane:ethyl acetate)to give 4-(3,5-dimethylpyridin-2-yl)-2-methylpiperazine-1-carboxylic acid tert-butyl ester (1.61 g). MS(ESI)m/z:206(M+H)+
