A mixture of 3-(6-chloro-1-ethyl-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-8-oxa-3-azabicyclo[3.2.1]octane (80 mg, 0.27 mmol), 5-indoylboronic acid (66 mg, 0.41 mmol), and tetrakis(triphenylphosphine)palladium(0) (35 mg, 10 mol %) in toluene/ethanol (1:1, 3 mL) and 2 M aqueous sodium carbonate solution (1 mL) was heated in a Smith process vial in the microwave reactor for one hour at 120° C. The cooled mixture was acidified with concentrated hydrochloric acid and then 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 to provide 1-ethyl-6-(1H-indol-5-yl)-4-(8-oxa-3-azabicyclo[3.2.1]oct-3-yl)-1H-pyrazolo[3,4-d]pyrimidine. MS (ES+): 375.2 (M+H)+
