Reaction Steps

Compound 6-chloro-3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazine (0.2 g, 0.638 mmol), 4-aminomethyltetrahydropyran (0.145 g, 0.956 mmol), Sodium tertiarybutyloxide (0.172 g, 1.785 mmol), rac-BINAP (0.024 g, 0.038 mmol) and Pd2(dba)3 (0.018 g, 0.019 mmol) were combined in a 20 ml vial. Toluene (5 mL) was added and nitrogen was bubbled through the mixture for 5 minutes. The reaction mixture was then heated to 100° C. overnight. Silica gel was added to the reaction mixture and the solvent stripped off. The product was isolated via column chromatography (hexanes:EtOAc) with the Compound N-((tetrahydro-2H-pyran-4-yl)methyl)-3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazin-6-amine eluting at 100% EtOAc.
