tert-Butyl 4-{4-[3-chloro-6-methoxy-2-methyl-5-(1-{[9-(tetrahydro-2H-pyran-2-yl)-9H-purin-6-yl]amino}ethyl)phenyl]-1H-pyrazol-1-yl}piperidine-1-carboxylate (0.040 g) was dissolved in CH2Cl2 (0.4 mL) and then TFA (0.4 mL) was added. The mixture was stirred at room temperature for 1 hour. After evaporated to dryness, the residue was purified on RP-HPLC (XBridge C18 Column, eluting with a gradient of acetonitrile in water with 0.05% trifluoroacetic acid, at flow rate of 30 mL/min) to give the desired product. LCMS calculated for C23H28ClN8O (M+H)+: m/z=467.2. found: 467.2.
