Reaction Steps

3-(Trifluoromethoxy)aniline (13 μL, 96 μmol), 1-chloro-6-methyl-N-(3-(6-(methylamino)pyrimidin-4-yl)pyridin-2-yl)isoquinolin-5-amine (33 mg, 88 μmol), tris(dibenzylideneacetone)dipalladium (0) (3 mg, 4 μmol), and 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl (3 mg, 7 μmol) were added to a microwave tube and suspended in THF-DMF (1:1, 1 mL). The tube was flushed with nitrogen and a solution of lithium bis(trimethylsilyl)amide, 1.0 M in hexanes (385 μL, 385 μmol) was added. The tube was heated in a microwave reactor at 150° C. for 15 min. The reaction mixture was partitioned between DCM and saturated aqueous sodium bicarbonate. The DCM layer was washed with brine, dried over sodium sulfate and concentrated. The residue was purified via preparative TLC on silica (DCM:EtOAc:EtOH:TEA=5:5:10:10) to give the desired product as a yellow solid. MS (M+H)+ 518.
