Procedure

To a solution of 2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-N-[(3S)-1-(1H-imidazol-2-ylmethyl)-3-piperidyl]pyrimidin-4-amine, 4a, (0.08 g, 0.13 mmol) in THF (2.5 mL) was added 1M LiOH (0.67 mL, 0.65 mmol) solution. The reaction mixture was heated in microwave at 120° C. for 10 minutes. The mixture was cooled to room temperature and diluted with brine. The aqueous phase was extracted with CH2Cl2, then twice with 20% isopropanol/CH2Cl2. The combined organic phases were dried (MgSO4), filtered and concentrated in vacuo to afford the desired product, 589, as a white solid.
