• Application

  4-Amino-2-bromo-6-methylpyridine can be used as an intermediate in organic synthesis. For example, the preparation of 2,4-dibromo-6-methylpyridine follows these steps: Bromine (2.57 g, 16.2 mmol) is added to a solution of 4-amino-2-bromo-6-methylpyridine (1.0 g, 5.4 mmol) cooled to -10 °C in 1.0 mL of 40% HBr aqueous solution, followed by the slow dissolution of sodium nitrite (1.86 g, 27.0 mmol) in 3.0 mL of water. The reaction mixture is warmed to room temperature and stirred for 3 hours. Subsequently, a saturated aqueous solution of sodium bicarbonate is added, and the reaction mixture is extracted with EtOAc (2 × 40 mL). The combined organic layers are washed with a saturated aqueous solution of sodium thiosulfate (2 × 40 mL) and water (2 × 40 mL). The organic layers are dried over sodium sulfate, filtered, and concentrated. The crude product was purified using a Redisep 12g silica gel column (0 to 100% EtOAc/hexane) to give 2,4-dibromo-6-methylpyridine as a colorless oil. XH NMR (300 MHz, CDCl3) Δδ 7.49 (d, J = 1.2 Hz, 1H), 7.28 (d, J = 1.2 Hz, 1H), 2.51 (s, 3H).;
