A screw-cap vial was charged with 4-chloro-5,7-difluoro-3-methyl-2-(2-(methylsulfonyl)phenyl)quinoline (50 mg, 0.136 mmol), 2-(methylsulfonyl)-5-morpholinoaniline (Matrix Scientific; 34.8 mg, 0.14 mmol), XPhos precatalyst (CAS 1028206-56-5; 10.0 mg, 0.014 mmol), sodium tert-butoxide (32.7 mg, 0.34 mmol), and toluene (1.5 mL). The mixture was stirred at 95° C. under nitrogen gas for 18 h. The reaction was then cond, and the resulting residue was dissolved in EtOAc. This solution was washed with water, and the product extracted twice with EtOAc and once with DCM. The combined organic layer was then dried over magnesium sulfate and cond, affording a crude residue that was purified by flash-chromatography (silica gel, 0-50% EtOAc in hexanes). This afforded 5,7-difluoro-3-methyl-N-(2-(methylsulfonyl)-5-morpholinophenyl)-2-(2-(methylsulfonyl)phenyl)quinolin-4-amine.
