2-Chloro-N-cyclopentyl-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (1 equiv), 4-hydroxyphenylboronic acid (1 equiv), potassium carbonate (2.5 equiv) and tetrakis(triphenylphosphine)palladium(0) (0.2 equiv), suspended in 1,4-dioxane/water, and flushed with nitrogen, were stirred at 100° C. for 16 h. The reaction mixture was loaded directly onto a silica gel column and purified using 5-100% ethyl acetate in hexane. Fractions containing desired product were combined and volatile organics were removed under reduced pressure to give 4-(2-chloro-4-(cyclopentylamino)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl)phenol (32.2% yield) as a yellow solid. MS (ESI) m/z 459.3 [M+1]+.
