2,3-DIBROMO-5-METHYLPYRIDINE Use and Manufacturing
In a 30-ml three-necked flask, 2-amino-3-bromo-5- methylpyridine (187 mg, 1.00 mmol) ) was charged, 48percent aqueous hydrogen bromide solution (1 ml) was added and 2-amino-3- bromo-5-methylpyridine was dissolved. Then, the mixture was ice-cooled, and bromine (154 μl, 3.00 mmol) was slowly added dropwise thereto at the internal temperature of 2 to 5°C. The mixture was stirred at the same temperature for 10 minutes. To this solution, sodium nitrite (174 mg, 2.5 mmol) /water (500 μl) solution was added dropwise at the same temperature, and the mixture was stirred for 1 hour. Sodium hydroxide (377 mg, 9.4 mmol) /water (2 ml) was slowly added dropwise thereto. The mixture was stirred at room temperature for 1 hour. The solution was poured into a separating funnel. The organic layer was separated by extraction using ethyl acetate (10 ml)
