74115-13-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 74115-13-2, name is 5-Bromo-3-pyridinol, the common compound, a new synthetic route is introduced below.
Step 2: Synthesis of 3-bromo-5-(2-fluoroethoxy)pyridine A solution of 1.0 g (5.75 mmol) 3-bromo-5-hydroxypyridine, 1.85 g (13.2 mmol) K2CO3, and 2.25 g (10.3 mmol) 2-fluoroethyl tosylate in 14 mL DMF was heated overnight at 60C. After cooling to room temperature the solvent was stripped on the oil pump, and the residue was taken up in 100 mL water and extracted three times each with 50 mL chloroform. After stripping the solvent the crude product was obtained, which was purified by column chromatography: 1: 500 mL CH2Cl2 2: CH2Cl2/CH3OH 98/2 1.04 g (4.73 mmol, 82.2% yield) of a yellow liquid was obtained. Product characteristics: Thin-layer chromatography (silica gel): Rf 3-bromo-5-hydroxypyridine (CH2Cl2) = 0.05 Rf 3-bromo-5-(2-fluoroethoxy)pyridine (CH2Cl2) = 0.25 1H-NMR (CDCl3): delta = 8.28 (d, 1H), 8.22 (d, 1H), 7.30 (t, 1H), 4.75 (t, 1H), 4.60 (t, 1H), 4.28 (t, 1H), 4.17 (t, 1H)
Statistics shows that 74115-13-2 is playing an increasingly important role. we look forward to future research findings about 5-Bromo-3-pyridinol.
