With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.185017-72-5, name is 3-Bromo-2-chloro-6-picoline, molecular formula is C6H5BrClN, molecular weight is 206.4676, as common compound, the synthetic route is as follows.name: 3-Bromo-2-chloro-6-picoline

In 21 mL of carbon tetrachloride, 3-bromo-2-chloro-6-methylpyridine (880 mg, 4.26 mmol) was dissolved, and N-bromosuccinimide (682 mg, 3.83 mmol) and AIBN (70 mg, 0.426 mmol) were added, followed by stirring at 90C for one hour. The resulting reaction solution was concentrated, and the residue thus obtained was purified by silica gel column chromatography (chloroform/methanol = 100/0 to 95/5), whereby 3-bromo-6-(bromomethyl)-2-chloropyridine was obtained as a crude purified product.
