Procedure

To a solution of 1-[(2R)-2-aminopropyl]-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-4-amine (1826.mg, 4.83 mmol), 2-cyanoacetic acid (821 mg, 9.7 mmol) and TEA (2.0 mL, 14.5 mmol) in DMF (25 mL) was added HATU (2.75 g, 7.24 mmol). The reaction mixture was stirred at room temperature for 20 hr. The mixture was then evaporated to an oil and dissolved in ethyl acetate (100 mL) and washed with 5% citric acid (50 mL) and brine. The organic layer was dried (MgSO4), filtered and evaporated. The crude material was purified by Isolera (10 g col, 2%-6% MeOH/DCM) to obtain 2.1 g (98%) of N-[(1R)-2-[4-amino-3-(2-fluoro-4-phenoxy-phenyl)pyrazolo[3,4-d]pyrimidin-1-yl]-1-methyl-ethyl]-2-cyano-acetamide.
