A mixture of N-[6-(3-aminophenoxy)imidazo[1,2-a]pyridin-2-yl]cyclopropanecarboxamide (20.0 mg, 0.065 mmol), 3-bromopyridine (14.4 mg, 0.091 mmol), tris(dibenzylideneacetone)2 palladium(0) (6.8 mg, 0.0074 mmol), 5-bis(diphenylphosphino)-9,9-dimethylxanthene (4.3 mg, 0.007 mmol), potassium t-butoxide (17.2 mg, 0.153 mmol) and toluene (2.0 mL) was stirred at 120° C. for 13 hr. The reaction mixture was diluted with aqueous sodium hydrogen carbonate solution and extracted with ethyl acetate. The organic layer was concentrated, and the residue was purified by preparative HPLC to give the title compound (3.0 mg, 12%).
