Direct intermolecular C-H arylation of 6-chloroimidazo[1,2-b]-pyridazine in its 3-position was achieved, and the tolerance to reaction conditions in the presence of chloro groups was investigated. Various 3-(hetero)arylimidazo[1,2-b]pyridazines were synthesized in good to excellent yields. This methodology was successfully applied to the synthesis of 3,6-di-and 2,3,6-trisubstituted imidazo[1,2-b]pyridazines
