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 (140 mg, 0.17 mmol) was treated with 2-(3-methoxybenzyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (100 mg, 0.17 mmol), cesium carbonate (164 mg, 0.50 mmols) and 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (14 mg, 0.02 mmol) according to the method described in Preparation 62. The residue was purified using SP1® Purification System (0% to 50%, hexane-ethyl acetate) to obtain 55 mg of the title compound. Purity 50%.
