Reaction Steps

The 6-chloro-7-methylimidazo[1,2-b]pyridazine 8 (0.230 g, 1.372 mmol) was taken in glacial acetic acid (10 ml) and bromine (0.070 ml, 1.372 mmol) was added slowly at room temperature. After 20 mins the solvents were evaporated the obtained brown solid was washed with ether (3×15 ml) and dried under air to furnish compound 9 (0.236 g, yield 69.8%).
