Reaction Steps

To a suspension of 6-(2-chloro-4-((tetrahydrofuran-3-yl)oxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methylbenzo[d]oxazole (1 equiv) in 1,4-dioxane (0.24 M) was added 4-amino-N,N,3-trimethylbenzamide (1 equiv), cesium carbonate (3 equiv), palladium acetate (0.3 equiv) and 2,2′-bis-diphenylphosphanyl-[1,1′]binaphthalene (0.6 equiv). The resulting reaction mixture was refluxed at 110° C. for 3 h. The reaction mixture was filtered and concentrated under reduced pressure. The crude product was purified by silica gel chromatography (5% MeOH in DCM) to afford the title compound (72% yield). MS (ESI) m/z 643.1 [M+H]+.
