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 (40 mg, 0.09 mmol) in dioxane (2 ml) were added 1-(2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3-(pyridin-4-yl)urea (62 mg, 0.14 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(11)dichloride dichloromethane complex (7.5 mg, 0.01 mmol) and 136 μl of a 2M aqueous solution of cesium carbonate. 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 product was purified by reverse phase using SP1® Purification System to give 25 mg (45% yield) as a white solid. Purity 97%.
