Versuchsvorschrift

A mixture of 3-(6-chloro-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (0.40 g, 1.4 mmol), 4-aminophenylboronic acid pinacol ester (0.47 g, 2.1 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.16 g, 10 mol %) in toluene/ethanol (1:1, 7 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 triturated with dichloromethane and the light brown solid was collected by Buchner filtration to furnish 4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-1-methyl-1H-pyrazolo[3,4-d]pyrimidin-6-yl)aniline. MS (ES+): 337.0 (M+H)+
