Adding a certain compound to certain chemical reactions, such as: 10320-42-0, 2-Chloro-5-nitropyrimidine, 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, Quality Control of 2-Chloro-5-nitropyrimidine, blongs to pyrimidines compound. Quality Control of 2-Chloro-5-nitropyrimidine
Acetic acid (15 mL, 261 mmol, 8 equiv) was slowly added to a stirred mixture of iron powder (11 g, 196 mmol, 6 equiv), 2-chloro-5-nitro-pyrimidine (5.3 g, 3 3. 33 m mol, 1 e quiv), a nd m ethanol (75 mL). Note: the reaction will exotherm if the acetic acid is added rapidly. After three hours, the reaction mixture was diluted with EtOAc (300 mL), filtered through celite, and neutralized with aqueous K2CO3 (200 mL). The organic layer was separated, washed with H20 (200 mL) and brine (200 mL), dried (NA2SO4), filtered, and concentrated to give 2 as a yellow solid (2.5 g, 58%, m/z+ = 130. 1).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,10320-42-0, 2-Chloro-5-nitropyrimidine, and friends who are interested can also refer to it.
