Reaction Steps
32.4 g (0.3 mole) of 6-aminopicoline was dissolved in a mixture of 28 g of conc. sulfuric acid and 120 ml of water and the resulting solution was cooled in ice water. 52.8 g (0.33 mole) of bromine was added dropwise to the solution over 30 minutes at 0° C. The reaction solution was stirred for 20 minutes at room temperature and neutralized with cold aqueous NaOH solution. The resultant was filtered and the solid was purified with column chromatography using methylene chloride and ethyl acetate as an eluent to obtain 31 g of the title compound (yield 55%).
