Triethylamine → (3-{3-[1-(4-Amino-3-bromo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-methoxy-6-methylphenyl}azetidin-1-yl)acetonitrile

To a mixture of 1-[1-(3-azetidin-3-yl-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-bromo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (100 mg, 0.2 mmol) and triethylamine (37 μL, 0.27 mmol) in acetonitrile (3 mL) was added bromoacetonitrile (19 μL, 0.27 mmol). The resulting mixture was stirred at room temp. After an hour, the reaction mixture was still cloudy with not all of the material in solution. Several drops of DMF were added which allowed for a clear solution. The mixture was stirred overnight at room temperature and then most of the solvents were evaporated. The resulting residue was purified on silica gel (eluted with 0-10% MeOH in dichloromethane) to give 29 mg (30%) of the desired product. LCMS calculated for C20H22BrClN7O (M+H)+: m/z=490.1; Found: 490.1.
