3-BROMO-2-HYDROXY-5-METHYLPYRIDINE Use and Manufacturing

5-Methyl-pyridin-2-ol (1 g, 9.16 mmol) was dissolved in 4 mL of CS2. Br2 (0.47 mL) was added thereto, andthe mixture was stirred at room temperature for 2 hours. Sodium thiosulfate (Na2S2O3) aqueous solution was addedthereto, and the reaction solution was extracted with EtOAc. The separated organic layer was dried with MgSO4 andconcentrated under reduced pressure to obtain the title compound (1.7 g, 98percent) in a solid form.1H-NMR (CDCl3) δ 7.73 (1H, s), 7.22 (1H, s), 2.10 (3H, s).3-Bromo-2-(difluoromethoxy)-5-methylpyridine 3-Bromo-2-(difluoromethoxy)-5-methylpyridine.
