As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 766-11-0, name is 5-Bromo-2-fluoropyridine, molecular formula is C5H3BrFN, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Recommanded Product: 5-Bromo-2-fluoropyridine
Phenol (8.02 g, 85.23 mmol) was dissolved in 50 ml of anhydrous tetrahydrofuran and stirred in an ice bath.Sodium hydride (2.5 g, 113.64 mmol) was gradually added and stirred for 30 min, and the reaction was continued at 80 C for 30 min.After cooling to room temperature, 2-fluoro-5-bromo-pyridine (10 g, 56.82 mmol) was added and refluxed at 80 C for 12 h.After the reaction was completed, it was cooled to room temperature, and the reaction was quenched with 100 ml of water, and extracted with ethyl acetate (100 ml×3).The organic phase was combined, washed with saturated brine, dried, filtered, and evaporated.Silica gel column chromatography gave 12.3 g of colorless oil, yield 86%.The elution system was petroleum ether: ethyl acetate = 100:1.
With the rapid development of chemical substances, we look forward to future research findings about 766-11-0.
