실험 절차

A 25 mL microwave pressure tube was charged 1-ethyl-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (105 mg, 0.363 mmol), 1-[(3-methylphenyl)acetyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-indole (137 mg, 0.363 mmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (14.83 mg, 0.018 mmol), and sodium bicarbonate (61.0 mg, 0.726 mmol) followed by dioxane (4 mL), and water (1 mL). The reaction was sealed and heated at 120° C. for 40 minutes in a microwave reactor. The reaction was cooled to room temperature, the mixture was transferred into a 100 mL flask, rinsed by EtOAc, with the water layer and black greasy solid stayed in tube (total 50 mL of EtOAc was added to the mixture). The EtOAc solution was evaporated to dryness, and re-dissolved with CH2Cl2/MeOH (4 mL/1 mL). It was purified by flash column 25-100% EtOAc/hexane, then 0-10% MeOH/EtOAc (Analogix Si SF15-24g cartridge), to afford a brown solid. The brown solid was further purified by recrystallization from CH3CN to give the title compound as a brown solid.
