An efficient one-pot protocol for conversion of easily accessible 3-nitropyridines to 3-acetamidopyridin-2-yl 4-methylbenzenesulfonate derivatives which were core structures of many pharmaceutical mols was reported. The strategy successfully combined a three-step reaction in one-pot via progressively adding different reactants at rt. The reaction displayed good functional group tolerance and regioselectivity. Structurally diversified 3-nitropyridine was time-efficiently (3.5 h) derivatized to various functional 2-O,3-N-pyridines which were apt for further elaborations. The transformation was amenable to gram-scale synthesis. After reading the article, we found that the author used 6-Bromopyridin-3-amine(cas: 13534-97-9Application In Synthesis of 6-Bromopyridin-3-amine)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. Amine, any member of a family of nitrogen-containing organic compounds that is derived, either in principle or in practice, from ammonia (NH3). Naturally occurring amines include the alkaloids, which are present in certain plants; the catecholamine neurotransmitters (i.e., dopamine, epinephrine, and norepinephrine); and a local chemical mediator, histamine, that occurs in most animal tissues.Application In Synthesis of 6-Bromopyridin-3-amine
