Adding a certain compound to certain chemical reactions, such as: 900789-14-2, 5-Bromo-2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine, 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, 900789-14-2, blongs to pyrimidines compound. Recommanded Product: 900789-14-2
(3) 200g of pure 5-bromo-2,4-dichloro-7H-pyrrolo [2,3-d] pyrimidine, 150g of zinc powder, 1000ml of acetic acid and 1000ml of ethanol are mixed, and the mixture is heated and refluxed after the mixing is completed 7h, filtered, distilled off ethanol, and sequentially dissolved in ethyl acetate, washed with saturated aqueous sodium bicarbonate solution, washed with saturated brine, dried, and evaporated to obtain 220 g of crude product; (4) The crude product obtained in step (3) was recrystallized from n-hexane to obtain pure 5-bromo-2-chloro-7H-pyrrolo [2,3-d] pyrimidine, with a purity of more than 98% and a yield of 94.5%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,900789-14-2, its application will become more common.
