To a suspension of methyl iodide (0.20 g, 0.41 mmol) and 3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]-cyclohexanol, 27a, (0.47 g, 2.04 mmol) was added silver oxide (0.578 g, 4.07 mmol and calcium sulfate (0.28 g, 2.04 (mmol). The reaction mixture was stirred at room temperature for 18 h. The mixture was filtered through celite and the resulting filtrate was concentrated in vacuo. The resulting crude mixture was purified by silica gel chromatography to afford 120 mg of the desired product, 27b.
