Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridineOn May 3, 2019 ,《Preparation of 1,5-Dihydropyrazolo[3′,4′:5,6]pyrano[3,4-b]pyridines via a Microwave-Assisted, Palladium-Catalyzed Regioselective C-H Heteroarylation of Electron-Rich Pyrazoles》 appeared in Journal of Organic Chemistry. The author of the article were Garrison, Aaron T.; Childress, Elizabeth S.; Davis, Dexter C.; Lindsley, Craig W.. The article conveys some information:
In the presence of Pd2(dba)3 and SPhos under microwave irradiation, bromopyridinylmethoypyrazoles such as I underwent regioselective arylation to yield dihydropyrazolopyranopyridines such as II; pyrazolobenzopyrans, pyrazolobenzothiopyrans, and two pyrazolonaphthyridinones were prepared using the same method. The cyclization precursors were prepared in two steps from methylpyridines or pyridinemethanols and pyrazolols. In the experimental materials used by the author, we found 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine(cas: 746668-59-7Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine)
6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine(cas: 746668-59-7) belongs to triazoles. The triazole ring is a relatively stable functional group, and the triazole bond can be used for a variety of applications, such as replacing the phosphate backbone of DNA.Reference of 6-Bromo-5-methyl[1,2,4]triazolo[1,5-a]pyridine
