Reaction Steps

A mixture of 6-(2-chloro-4-cyclopropoxy-7-((2-(trimethylsilyl)- ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methylbenzo[d]oxazole (1 equiv), 4-amino-3-methoxy-N-methylbenzamide (2 equiv), potassium carbonate (3.5 equiv), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.23 equiv), tris(dibenzylideneacetone)dipalladium (0.23 equiv) in 1,4-dioxane (0.085 M) was purged with nitrogen and sealed. The reaction mixture was heated to 140° C. for 1.5 h. After cooling to room temperature the reaction mixture was purified using flash chromatography (0-100% ethyl acetate in hexane then 0-20% methanol in DCM) eluted with 17% methanol in DCM to give the title compound (57.5% yield) as brown oil. MS (ESI) m/z 615.4 [M+1]+.
