The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines. Pinner first proposed the name “pyrimidin” in 1885. 4595-59-9, formula is C4H3BrN2, Name is 5-Bromopyrimidine. The parent compound was first prepared by Gabriel and Colman in 1900, by conversion of barbituric acid to 2,4,6-trichloropyrimidine followed by reduction using zinc dust in hot water. Recommanded Product: 5-Bromopyrimidine.
Song, Geyang;Nong, Ding-Zhan;Li, Jing-Sheng;Li, Gang;Zhang, Wei;Cao, Rui;Wang, Chao;Xiao, Jianliang;Xue, Dong research published 《 General Method for the Amination of Aryl Halides with Primary and Secondary Alkyl Amines via Nickel Photocatalysis》, the research content is summarized as follows. It was reported that Ni(II)-bipyridine complex catalyzed efficient C-N coupling of aryl chlorides and bromides with various primary and secondary alkyl amines under direct excitation with light. Intramol. C-N coupling was also demonstrated. The feasibility and applicability of the protocol in organic synthesis was attested by more than 200 examples.
Recommanded Product: 5-Bromopyrimidine, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., 4595-59-9.
