Adding a certain compound to certain chemical reactions, such as: 62802-42-0, 2-Chloro-5-fluoropyrimidine, 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, 62802-42-0, blongs to pyrimidines compound. COA of Formula: C4H2ClFN2
General procedure: Under nitrogen, a solution of sodium carbonate (4.24g, 40 mmol) in water (20 mL) was added to asolution of 2-chloro-5-fluoropyrimidine 4 (2.47 mL, 20 mmol) in toluene (60 mL), and the mixture washeated to 80 C. Bis(triphenylphosphine)palladium(II) chloride (701.9 mg, 1 mmol) was added, and asolution of 3-(hydroxymethyl)phenylboronic acid (3.34 g, 22 mmol) in ethanol (20 mL) wassubsequently added dropwise. The reaction mixture was stirred at 90 C for 12 hours. The reactionmixture was cooled to room temperature and filtered. The aqueous phase was extracted with AcOEt(100 mL x 3). The combined organic layer was washed with H2O (30 mL) and brine (20 mL), and thendried over anhydrous Na2SO4, filtered and evaporated in vacuo. The residue was purified by flashchromatography over silica gel (petroleum/EtOAc = 10:13:1) to give(3-(5-fluoropyrimidin-2-yl)phenyl)methanol 5 (68%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,62802-42-0, its application will become more common.
