실험 절차

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 90° C. 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.
