Reaction Steps

In a reaction vial was placed a stir bar, 1-[2-(2-dimethylamino-ethoxy)-4-methanesulfonyl-phenyl]-1H-pyrazolo[3,4-d]pyrimidin-4-ol (50 mg), POCl3 (0.5 mL) and N,N-dimethylaniline (15 μl). The reaction mixture was stirred at 100° C. for 1 hour. Upon cooling the reaction mixture to the room temperature, a white precipitate formed. The mixture was left sealed over the weekend at room temperature. After concentrated under the vacuum, the residue was washed with Et2O and filtered to give {2-[2-(4-chloro-pyrazolo[3,4-d]pyrimidin-1-yl)-5-methanesulfonyl-phenoxy]-ethyl}-dimethyl-amine as a white solid. Exact mass calculated for C16H18ClN5O3S 395.08, found 396 (MH+).
