실험 절차
6-chloroimidazo[1,2-b]pyridazine (2.0 g, 13.0 mmol, 1.0 equiv) in chloroform (20 mL) at room temperature was added N-iodosuccinimide (2.9 g, 13.0 mmol, 1.0 equiv) then stirred vigorously overnight. The reaction mixture was diluted in water and extracted with ethyl acetate. Purification using column chromatography gave 3.3 g of the yellow solid, 90%: 1H NMR δ 8.21 (d, J=7.6 Hz, 1H), 7.96 (s, 1H), 7.41 (d, J=7.6 Hz, 1H).
