Procedure
To a solution of N-(3-(5-bromo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)phenyl)methacrylamide (249 mg, 0.51 mmol) in toluene (10 mL) under nitrogen, was added 2-(tributylstannyl)-1,3-oxazole (548 mg, 1.53 mmol), Pd2(dba)3 (93 mg, 0.10 mmol), and X-Phos (95 mg, 0.20 mmol). The resulting solution was stirred overnight at 60° C. and then concentrated in vacuo, and the resulting crude reaction was extracted with ethyl acetate (×3). The combined organic layers were washed with brine, dried with anhydrous sodium sulfate, filtered and concentrated in vacuo. The reaction was then purified by chromatography using silica gel, eluting with 0-100% EtOAc/petroleum ether. The product was collected and concentrated in vacuo to afford N-(3-(5-(oxazol-2-yl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl)phenyl)methacrylamide as a yellow oil. LRMS (ESI) calc'd for C25H30N5O3Si [M+H]+: 476, found 476.
