Reaction Steps
A 100 mL RB flask was charged with 2-bromo-1-(quinolin-6-yl)ethanone (0.7011 g, 2.80 mmol), (E)-N′-(6-chloropyridazin-3-yl)-N,N-dimethylformamidine (0.518 g, 2.80 mmol), and DMF (10.0 ml, 129 mmol), equipped with a reflux condenser, then heated at 105° C. for 3 hours. The reaction mixture was concentrated, then triturated with MeOH to yield (6-chloroimidazo[1,2-b]pyridazin-3-yl)(quinolin-6-yl)methanone (0.530 g, 1.72 mmol, 61%) as a brown solid.
