実験手順
2-(2-bromo-5-trityl-pyrrolo[2,3-b]pyrazin-7-yl)-7-chloro-isoindolin-1-one (150 mg, 0.2476 mmol), tert-butyl 4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]sulfonylpiperidine-1-carboxylate (112 mg, 0.2476 mmol) and Na2CO3 (371 μL of a 2.0 M aqueous solution, 0.7428 mmol) combined in 1,4-dioxane (3 mL) under N2. Mixture de-gassed (×3 vacuum-N2 cycles) then Pd(PPh3)4 (14 mg, 0.01238 mmol) added. Reaction mixture de-gassed (×3 cycles) and stirred overnight at 110° C. Reaction cooled and partitioned between DCM and water. Aqueous phase extracted with DCM and combined organics dried and concentrated. Residue purified by chromatography (silica, 0-100% EtOAc-petroleum ether gradient elution). Title compound obtained as a yellow solid (186 mg, 88%), taken directly on to deprotection reaction; MS (ES+) 850.0.
