Reaction Steps

CsF (50 mg, 0.33 mmol) was added to the mixture of 6-chloro-3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazine (150 mg, 0.48 mmol) and 4-(aminomethyl)-1-methylpiperidin-4-ol (150 mg, 1.04 mmol) in DMSO (1.5 mL). The mixture was heated to 120° C. over night and partitioned with EtOAc (10 mL) and water (10 mL). The organic layer was washed with brine (8 mL×3), dried with Na2SO4 and concentrated under reduced pressure. The residue was purified by pre-HPLC to give the product 1-methyl-4-(((3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazin-6-yl)amino)methyl)piperidin-4-ol (22 mg, 10%)
