To a solution of tert-butyl 4-((2-(2-ethyl-1H-benzo[d]imidazol-1-yl)-9-methyl-6-morpholino-9H-purin-8-yl)(hydroxy)methyl)piperidine-1-carboxylate (0.320 g, 0.555 mmol) in Methylene chloride (10 mL, 200 mmol;) was added Trifluoroacetic Acid (0.50 mL, 6.5 mmol;). The reaction was stirred at room temperature for 1 hr. and the reaction mixture was evaporated to dryness. To the residue was added 2M NH3 in MeOH to neutralize any residual acid. The mixture was then evaporated to dryness. The crude was then purified by flash chromatography (0-15% MeOH in DCM) to give the desired product as pinkish paste (0.24 g, 91%). LCMS m/z 477.4 (MH+).
