Procedure

A mixture of 4-(2-chloro-4-(cyclopentylamino)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)phenol (1 equiv), 4-amino-3-methoxy-N-methylbenzamide (1 equiv), potassium carbonate (2.5 equiv), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.2 equiv), and tris(dibenzylideneacetone)-dipalladium (0.2 equiv) in 1,4-dioxane (0.13 M) was purged with nitrogen and sealed. The reaction mixture was heated to 130° C. for 1.5 h. The reaction was filtered and solvents were removed under reduced pressure. The reaction mixture was loaded directly onto a silica gel column and purified using 15-100% ethyl acetate in hexane, followed by 100% ethyl acetate. Fractions containing desired product were combined and volatile organic solvents were removed under reduced pressure to give the title compound (29.2% yield) as a brown oil. MS (ESI) m/z 603.5 [M+1]+.
