2-Chloro-3-methyl-5-bromopyridine Use and Manufacturing
The product from Example 49A (4.1 g, 221.8 mmol) in DMF (40 mL) was treated with phosphorous oxychloride (10 g, 65.4 mmol) dropwise at 0 °C. The resulting solution was heated at 120 °C for 2 hours, cooled and poured onto ice/H2O. The mixture was made basic with NH4OH. The precipitate was filtered, washed with ice water, dissolved in dichloromethane (100 mL), washed with brine, and dried (MgSO4). The solution was filtered through a pad of silica (dichloromethane) and concentrated to leave the title compound as a white solid (3.48 g, 78percent). MS (DCI/NH3) m/z 348 (M+H)+.
