Reaction Steps

(S)-2-(1-((5-Bromo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (57 mg, 0.10 mmol) was treated with (1H-pyrazol-4-yl)boronic acid (64 mg, 0.58 mmol), sodium carbonate (65 mg, 0.61 mmols) and bis(triphenylphosphine)palladium(II) dichloride (33 mg, 0.03 mmol) according to the method described in Preparation 62. The residue was purified using SP1® Purification System (0% to 100%, hexane-ethyl acetate) to give 23 mg (41% yield) of the title compound. Purity 99%.
