Reaction Steps

To a solution 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 (100 mg, 0.21 mmol) were added 70 mg (0.32 mmol) of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-amine, 19 mg (0.02 mmol) of 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex and 317 μl of a 2M aqueous solution of sodium carbonate in dioxane. The mixture was stirred under argon atmosphere at 80° C. for 18 hours and then diluted with ethyl acetate. The resulting solution was washed with water and brine, dried over magnesium sulphate, filtered and the solvents were removed under reduced pressure. The product was purified first by flash chromatography (0% to 15% MeOH/DCM) and then by reverse phase chromatography (C-18 silica from Waters®, water/1:1 acetonitrile-methanol as eluents [0.1% v/v formic acid buffered] 0% to 100%) to give 28 mg (30% yield) of the title compound as a white solid.
