To a Smith process vial containing a suspension of 4-chloro-6-(4-nitro-phenyl)-1-(2,2,2-trifluoro-ethyl)-1H-pyrazolo[3,4-d]pyrimidine (0.30 g, 0.84 mmol) and (1S,4S)-2-oxa-5-azabicyclo[2.2.1]heptane hydrochloride (0.12 g, 0.88 mmol) in ethanol (4 mL) was added triethylamine (0.33 mL, 2.5 mmol). The mixture was heated in the microwave reactor for 15 minutes at 120° C. The precipitate was collected by Buchner filtration, washed with methanol, and dried under house vacuum to provide (1S,4S)-5-(6-(4-nitrophenyl)-1-(2,2,2-trifluoroethyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-2-oxa-5-azabicyclo[2.2.1]heptane as a bright yellow powder (0.42 g, >100%).
