Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 92992-85-3, name is 2-Bromo-3,5-dimethylpyridine. A new synthetic method of this compound is introduced below., Recommanded Product: 92992-85-3
To 2-bromo-3,5-dimethylpyridine (1 g) were added 1-(tert-butoxycarbonyl)-3-aminoazetidine (1.11 g),tris(dibenzylideneacetone)dipalladium(0)(250 mg),2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (330 mg),sodium tert-butoxide (770 mg) and toluene (8 mL) and the mixture was stirred at 120c overnight. The reaction mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The obtained residue was purified by NH column chromatography (hexane:ethyl acetate)to give the title compound (965 mg). MS(APCI)m/z:278(M+H)+
