Adding a certain compound to certain chemical reactions, such as: 17282-01-8, 3-Bromo-2-fluoro-5-picoline, 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, 17282-01-8, blongs to pyridine-derivatives compound. Recommanded Product: 3-Bromo-2-fluoro-5-picoline
Preparation 98: 5-(2-Fluoro-5-methylpyridin-3-yl)-2,4-dimethoxy-pyrimidine (Prep98); 2,4-Dimethoxy-pyrimidine-5-boronic acid (842 mg, 4.60 mmol) was dissolved in degassed n-PrOH (55 ml) and then 2-fluoro-3-bromo-5-methylpyridine (800 mg, 4.21 mmol), Na2CO3 (1.46 g, 13.77 mmol), PPh3 (348 mg, 1.33 mmol) and Pd(OAc)2 (101 mg, 0.45 mmol) were added. The suspension was stirred at reflux for 2 hours. After cooling, the solvent was evaporated under vacuum and the crude was partitioned between water and ethyl acetate. The organic phase was dried (Na2SO4) and evaporated. The residue was triturated with Et2O to give 350 mg of the title compound as a gray powder (31 % yield). MS (ES) (mlz): 250.2 [IvRH]+.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,17282-01-8, its application will become more common.
