반응 단계
A solution of 6-chloro-3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazine (0.3 g, 0.96 mmol) and cyclohexanediol (0.11 g, 0.96 mmol) in toluene 5 mL was added potassium tertiary butoxide (0.165 g, 1.72 mmol), rac-BINAP (36 mg, 0.057 mmol) and Pd2(dba)3 (26 mg, 0.029 mmol) and the mixture was heated at 120° C. for 4 h under microwave irridation. The resulting dark brown solution was cooled down and was concentrated under reduced pressure. The solid was further purified by using combiflash chromatography (12 g column), eluent: 0-10% methanol/DCM and obtained product 4-((3-(3-(trifluoromethoxy)phenyl)imidazo[1,2-b]pyridazin-6-yl)oxy)cyclohexanol (50 mg, 0.127 mmol, 13% yield).
