A 48 mL sealed tube was charged with (6-chloroimidazo[1,2-b]pyridazin-3-yl)(quinolin-6-yl)methanone (0.530 g, 1.72 mmol), phenylboronic acid (0.314 g, 2.58 mmol), cesium carbonate (1.68 g, 5.15 mmol), PdCl2(dppf)-CH2Cl2 adduct (0.0701 g, 0.0858 mmol), 1,4-dioxane (6.31 ml, 73.8 mmol), and water (1.11 ml, 61.8 mmol), flushed with argon, sealed, then placed in an 80° C. oil bath for 8 hours. The mixture was concentrated then triturated with water, followed by MeOH/DCM to give (6-phenylimidazo[1,2-b]pyridazin-3-yl)(quinolin-6-yl)methanone as a reddish brown solid.
