3-Bromo-2-chloro-6-methyl-5-nitropyridine Use and Manufacturing
3-Bromo-6-methyl-5-nitropyridin-2-ol (9.2 g, 36.7 mmol) in POClPreparation 13D: 3 -bromo-2-chloro-6-methyl-5 -nitropyridine [00276j In a 500-mL single round-bottomed flask, POC13 (12 g, 78.1 mmol) was added dropwise to 3-bromo-6-methyl-5-nitropyridin-2-ol (4 g, 15.87 mmol). This mixture was then stirred at reflux for 7 h. The reaction mixture was cooled to 30 °C, poured into ice water and stirred for 10 mm. Saturated NaHCO3 solution (30 mL) was then added. The aqueous layer was extracted with EtOAc (200 mL x 3). The combined organic layers were washed with water, brine (200 mL x 2), dried over Na2504, filtered and concentrated to give 2.8 g (65 percent) of the title compound as a yellow solid. ‘H NMR (400 MHz, CDC13) ö 8.55 (s, 1 H), 2.83 (s, 3 H).In a 500-mL single round-bottomed flask, POCI3-Bromo-6-methyl-5-nitropyridin-2-ol (9.2 g, 36.7 mmol) in POClPreparation 13D: 3 -bromo-2-chloro-6-methyl-5 -nitropyridine [00276j In a 500-mL single round-bottomed flask, POC13 (12 g, 78.1 mmol) was added dropwise to 3-bromo-6-methyl-5-nitropyridin-2-ol (4 g, 15.87 mmol).
