Procedure

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, (0.25 g, 0.50 mmol) in DMF was added tert-butylbromoacetate (0.08 mL, 0.55 mmol) and Na2CO3 (0.11 g, 0.99 mmol). The reaction mixture was stirred at room temperature for 6 h. The resulting thick white precipitate was diluted with aqueous saturated NaCl solution and washed with water. The white solid was dissolved in CH2Cl2 and the solution was dried (MgSO4), filtered and concentrated in vacuo. The crude was purified via silica gel chromatography (0%-5% MeOH/CH2Cl2) to afford the desired product, 2a, as a white solid.
