Participants

Reaction Steps

To a solution of 3-(imidazo[1,2-b]pyridazin-6-yloxy)aniline (113 mg, 0.50 mmol) and triethylamine (0.040 mL, 0.29 mmol) in tetrahydrofuran (10 mL) was added 4-(trifluoromethyl)phenyl isocyanate (0.100 mL, 0.70 mmol), and the mixture was stirred at room temperature for 18 hr. The reaction mixture was concentrated under reduced pressure, and the residue was precipitated from methanol to give the title compound (103 mg, 50%) as a white powder.
