Reaction Steps

In step 2-5, a suspension of 3-(3-fluorophenyl)morpholine (1.59 g, 6.9 mmol), 3-bromo-6-chloroimidazo[1,2-b]pyridazine (12-1) (1.5 g, 8.29 mmol) and potassium fluoride (1.6 g, 27.6 mmol) in DMSO (6 mL) was heated at 180° C. for 18 hours while stirring. The resulting solution was cooled to room temperature and purified with HPLC to yield 4-(3-Bromoimidazo[1,2-b]pyridazin-6-yl)-3-(3-fluorophenyl)morpholine (2-5) as a yellow foam.
