실험 절차
To a solution of 6-chloro-2-methylimidazo[1,2-b]pyridazine (2.00 g, 11.9 mmol, 1.0 equiv) in chloroform (50 mL) was added N-bromosuccinimide (2.55 g, 14.3 mmol, 1.2 equiv). The reaction was stirred at room temperature for 15 h. Purification by column chromatography using 50% ethyl acetate in hexanes elution gave 2.64 g of the yellow solid, 90%.
