Procedure

To a solution of (S)-2-(1-((6-amino-5-bromopyrimidin-4-yl)amino)ethyl)-5-methyl-3-phenylpyrrolo[2,1-f][1,2,4]triazin-4(3H)-one (120 mg, 0.27 mmol) were added (1H-indol-6-yl)boronic acid (65 mg, 0.41 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(11)dichloride dichloromethane complex (22 mg, 0.03 mmol) and 272 μl of a 2M aqueous solution of cesium carbonate in dioxane (2 ml). The mixture was stirred under argon atmosphere at 100° 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 crude was purified using SP1® Purification System (50% to 100%, hexane-ethyl acetate) to obtain 125 mg (94% yield) of the title compound as a white solid. Purity 98%.
