Adding a certain compound to certain chemical reactions, such as: 1337962-47-6, 5-Bromo-2,6-di(1H-pyrazol-1-yl)pyrimidin-4-amine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 1337962-47-6, blongs to pyrimidines compound. Quality Control of 5-Bromo-2,6-di(1H-pyrazol-1-yl)pyrimidin-4-amine
To a suspension of 50mg (0.1633 mmol) of 5-bromo-2,6-di(1H-pyrazol-1-yl)- pyrimidin-4-amine (Form F) in lmL ethyl acetate was added 54.5uL HC1 aqueous solution (6M, 0.3266 mmol) dropwise. The mixture was stirred at 50 degree C for 20 hours. The mixture was cooled to room temperature within 2 hours and the stirring was maintained for another 1 hour. The solid was collected with vacuum filtration and dried at r.t overnight. 5-bromo-2,6-di(1H- pyrazol-1-yl)-pyrimidin-4-amine di-hydrochloride hydrate was obtained as a crystalline Form B. The solid was analyzed by XRPD after isolation.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1337962-47-6, its application will become more common.
