Reaction Steps

The title compound was prepared following the experimental procedure described in Example 3 from 100 mg (0.21 mmol) of (S)-2-(1-((6-amino-5-iodopyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one and 76 mg (0.32 mmol) of 2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)ethanol. After 18 hours heating, an excess of 2-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)ethanol (76 mg), palladium catalyst (19 mg) and aqueous sodium carbonate solution (317 μl) were added and the reaction mixture was stirred at 80° C. for 24 hours more. The product was purified by flash chromatography (0% to 15%, dichloromethane-methanol) to obtain 46 mg (48% yield) of the title compound.
