Procedure

5-fluoro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 44c, (5.9 g, 10.5 mmol) and tert-butyl N-[(1R,3S)-3-aminocyclohexyl]carbamate (3 g, 12.60 mmol) were dissolved in THF (100 mL). The reaction mixture was heated to 50° C. for 6 hours, then cooled to room temperature. Celite was added and the solvent was removed under reduced pressure. The Celite-supported residue was purified by silica gel chromatography (20-80% EtOAc/hexanes gradient to provide 3.7 g of tert-butyl N-[(1R,3S)-3-[[5-fluoro-2-[5-fluoro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]cyclohexyl]carbamate.
