With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.120737-78-2,tert-Butyl 2-methylpiperazine-1-carboxylate,as a common compound, the synthetic route is as follows.
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)+
120737-78-2, The synthetic route of 120737-78-2 has been constantly updated, and we look forward to future research findings.
