Versuchsvorschrift
2,6-Dichloroimidazo[1,2-b]pyridazin-3-ylsulfonamide (2.00 g, 6.22 mmol) and N,N-Dimethylformamide dimethyl acetal (1.80 ml, 13.5 mmol) were heated under reflux for 4 hours in toluene (20.0 ml). The resulting reaction solution was left to cool to room temperature, and concentrated to dryness under reduced pressure to give the title compound as pale yellow crystals. The yield was 2.36 g (100%).
