Reaction Steps

A solution of 9-bromo-5-{[2,6-dichloro-4-(1H-pyrazol-5-yl)phenyl]amino}benzo[c]-2,6-naphthyridin-1(2H)-one (125 mg, 0.25 mmol) in DMF (3 mL) was degassed with nitrogen. Triethylamine (0.07 ml, 0.50 mmol), 2-methylbut-3-yn-2-ol (42.0 mg, 0.499 mmol), Pd(Ph3P)4 (28.8 mg, 0.025 mmol) and copper(I) iodide (9.50 mg, 0.050 mmol) were added and the reaction was heated to 75° C. for 16 h. After cooling to room temperature, the reaction was diluted with ethyl acetate and extracted with water. The organic layer was dried with sodium sulfate, filtered and concentrated under reduced pressure. The residue was dissolved in THF/MeOH, filtered and purified by reverse phase HPLC to afford the title compound.
