A Smith process vial was charged with a suspension of 3-(4-bromo-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenol (0.15 g, 0.41 mmol) and 8-oxa-3-azabicyclo[3.2.1]octane hydrochloride (approximately 1 mmol) in ethanol (5 mL). The suspension was treated with triethylamine (500 μL, 3.8 mmol) and was then heated in the microwave reactor for 10 minutes at 180° C. The reaction mixture was concentrated to dryness under reduced pressure, and the residue was purified by reverse-phase high performance liquid chromatography using a Phenomenex Prodigy 21 mm×250 mm column, running a gradient elution of 15% acetonitrile/88% of 0.1% aqueous trifluoroacetic acid to 100% acetonitrile to provide 3-[4-(8-oxa-3-azabicyclo[3.2.1]oct-3-yl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl]phenol. MS (ES+): 400.1 (M+H)+
