Adding a certain compound to certain chemical reactions, such as: 57054-92-9, 5-Bromo-2-chloro-4-methoxypyrimidine, 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, 57054-92-9, blongs to pyrimidines compound. Product Details of 57054-92-9
4-Methoxypyrimidine5-Bromo-2-chloro-4-methoxypyrimidine (5.00 g, 22.38 mmol) and 10% Pd/C (2.381 g, 2.24 mmol) and ammonium formate (8.47 g, 134.26 mmol) were stirred in methanol (50 mL) at room temperature for three hours. The reaction mixture was filtered through Celite to get rid of Pd/C, and the filtrate was evaporated to dryness. The residue was dissolved in methylene chloride, washed with water once, dried through MgSO4, filtrated and evaporated to dryness to give a yellow liquid as the title compound (2.25 g, 91.1%). The crude material was used as such without further purification.1H NMR (300 MHz, CHLOROFORM-d) delta ppm 8.79 (s, 1 H) 8.41 (d, J=5.7 Hz, 1 H) 6.73 (dd, J=5.8, 1.2 Hz, 1 H) 3.99 (s, 3 H). MS APCI, m/z=152 (M+ACN+H). HPLC 0.73 min.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,57054-92-9, its application will become more common.
