Reaction Steps

Place 4-Chloro-1H-pyrazolo[3,4-d]pyrimidine (150 mg; 1.16 equiv; 970.50 μmoles; 150.00 mg), and 4-[4-(3-Nitro-phenyl)-1H-imidazol-2-yl]-piperidine hydrochloride salt (258 mg 1.00 equiv; 835.58 μmoles; 258.00 mg) in a microwave vial and dissolve in isopropyl alcohol (3 mL; 39.24 mmoles; 3.00 mL) and add diisopropylethylamine (0.5 mL; 2.87 mmoles; 500.00 μL). Heat the mixture to 70° C. in a Emrys Optimizer microwave for 1 hour while stirring. Filter, and concentrate filtrate to an oil. Combine solid and oil and dissolve in 3% MeOH/DCM. Purify using ISCO chromatography over a biotage 40S column eluting with a gradient of 2.5% MeOH/DCM to 10% MeOH/DCM at a flow rate of 40 mL/min. Collect appropriate fractions, concentrate to an oil. Dissolve oil in 10% MeOH/DCM and wash with a mixture of aqueous sodium bicarbonate/saturated aqueous sodium chloride three times. Wash the combined organic layers with saturated aqueous sodium chloride and dry over sodium sulfate. Concentrate and dry under reduced pressure to obtain the title compound.
