Procedure
A mixture of 6-(2-chloro-4-(cyclopentyloxy)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-4-fluoro-2-methylbenzo[d]oxazole (1 equiv), 4-amino-3-methoxy-N-methylbenzamide (1.2 equiv), brettphos (0.15 equiv), cesium carbonate (3 equiv), and dicyclohexyl(2′,6′-diisopropoxy-[1,1′-biphenyl]-2-yl)phosphine (0.15 equiv) in 1,4-dioxane (0.2 M) was purged with nitrogen and sealed. The reaction mixture was heated to 110° C. for 2 h. The reaction was filtered and solvents were removed under reduced pressure. The reaction mixture was purified using silica gel chromatography (0 to 100% ethyl acetate in hexane) to give the title compound (63% yield). MS (ESI) m/z 661.5 [M+H]+.
