To a solution of 2-chloro-5-(2,6-difluorophenyl)-6H-pyrido[1,2-b]pyridazin-6-one (100 mg, 0.34 mmol) dissolved in toluene (1.5 mL) was added Pd(DBA) (3.1 mg, 0.0034 mmol), dppf (3.7 mg, 0.0068 mmol), sodium butoxide (23 mg, 0.238 mmol), and 2,4 difluoro aniline (43 mg, 0.34 mmol). The reaction was heated to 80° C. for 3 hours until complete by LCMS analysis. The reaction was passed through celite, condensed to an oil and purified via silica gel chromatography (EtOAc/CH2Cl2, MeOH) to yield the title compound.
