Sodium Chloride → (2-(5-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-ylamino)-1-methylcyclohexanol

To a solution of 5-chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 1a, (0.97 g, 2.09 mmol) and 2-amino-1-methylcyclohexanol, 30b, (0.40 g, 3.13 mmol) in DMF (10 mL) was added iPr2NEt (0.73 mL, 4.17 mmol). The reaction mixture was heated at 90 C for 17 hours. The reaction mixture was cooled to room temperature and diluted into aqueous saturated NaCl solution. The aqueous phase was extracted twice with EtOAc. The organic phases were washed with twice with aqueous saturated NaCl solution, dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified via silica gel chromatography (0-50% EtOAc/hexanes-loaded with CH2Cl2) to afford the desired product, 30c, as a white solid.
