Versuchsvorschrift

To a solution of 6-chloro-3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazine (300 mg, 0.96 mmol) and 4-amino-2-methylbutan-2-ol hydrogenchloride (493 mg, 4.78 mmol) in NMP (2.0 mL) was added NaHCO3 (516 mg, 4.78 mmol), the mixture was stirred at 180° C. for 45 mins under microwave irridation. The mixture was purified by flash chromatograph to give 2-methyl-4-((3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazin-6-yl)amino)butan-2-ol (175 mg, 48%) as a pale yellow solid.
