Reaction Steps

A mixture of N-[3-({2-[(chloroacetyl)amino]imidazo[1,2-b]pyridazin-6-yl}oxy)phenyl]-3-(trifluoromethyl)benzamide (120 mg, 0.244 mmol), aqueous dimethylamine (3 mL) solution and acetonitrile (3 mL) was heated to 80° C. and stirred for 3 hr. After the reaction mixture was allowed to cool to room temperature, saturated aqueous sodium hydrogencarbonate solution was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtrated. The solvent was evaporated under reduced pressure, and the residue was washed with ethanol to give the title compound (85 mg, 70%) as a pale-yellow powder.
