Versuchsvorschrift

To a solution of 2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[5,4-b]pyridin-3-yl]-5-fluoro-N-[(3S)-3-piperidyl]pyrimidin-4-amine, 1c, (0.17 g, 0.34 mmol) in DMF (1.5 mL) was added 2,2,2-trifluoroethyl trichloromethanesulfonate (0.19 g, 0.68 mmol), followed by iPr2NEt (0.24 mL, 1.36 mmol). The reaction mixture was stirred at room temperature for 18 h. The mixture was poured into brine and extracted twice with EtOAc. The combined organic phases were washed twice with brine, dried (MgSO4), filtered, and concentrated in vacuo. The crude residue was purified by silica gel chromatography (0-10% MeOH/CH2Cl2) afforded the desired product, 3a, as a white solid.
