実験手順
A mixture of 3-(6-chloro-1-(1-(2,2,2-trifluoroethyl)piperidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (0.55 g, 1.3 mmol), 4-aminophenylboronic acid pinacol ester (0.42 g, 1.9 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.15 g, 10 mol %) in toluene/ethanol (1:1, 10 mL) and 2 M aqueous sodium carbonate solution (2 mL) was heated in a 10-20 mL Smith process vial in the microwave reactor for one hour at 120° C. The cooled mixture was partitioned between ethyl acetate and water. The aqueous phase was extracted three times with ethyl acetate. The combined extracts were washed with saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, filtered, and concentrated to dryness under reduced pressure. The crude residue was purified via reverse-phase high performance liquid chromatography using a Phenomenex Prodigy 21 mm×250 mm column, running a gradient elution of 10% acetonitrile/90% of 0.1% aqueous trifluoroacetic acid to 95% acetonitrile over 30 minutes. After the concentration of fractions under reduced pressure, 4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-1-(1-(2,2,2-trifluoroethyl)piperidin-4-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl)aniline was obtained as a maroon oil that solidified upon standing. MS (ES+): 488.4 (M+H)+
