Triethylamine → 3-(4-(3-oxa-8-azabicyclo[3.2.1]octan-8-yl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenol

A Smith process vial was charged with a suspension of 3-(4-bromo-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenol (0.18 g, 0.49 mmol) and 3-oxa-8-azabicyclo[3.2.1]octane hydrochloride (approximately 100 mg, 0.67 mmol) in ethanol (4 mL). The suspension was treated with triethylamine (750 μL, 5.7 mmol) and was then heated in the microwave reactor for 10 minutes at 130° 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 20% acetonitrile/80% of 0.1% aqueous trifluoroacetic acid to 100% acetonitrile to provide 3-(4-(3-oxa-8-azabicyclo[3.2.1]octan-8-yl)-1-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenol. MS (ES+): 400.3 (M+H)+
