実験手順

A solution of (R)-tert-butyl 5-bromo-4-(3-(tert-butoxycarbonylamino) piperidin-1-yl)-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (175 mg, 0.303 mmol) in dioxane (5 mL) at room temperature was treated with potassium carbonate (107 mg, 0.771 mmol), Pd(PPh3)4 (31.5 mg, 0.0272 mmol), and 2,4,6-trimethyl-1,3,5,2,4,6-trioxatriborinane (34.2 mg, 0.272 mmol). N2 was bubbled through the mixture for 5 minutes, and the mixture was heated at reflux for 24 hours under N2 atmosphere. The mixture was then diluted with EtOAc (20 mL) and washed with water (1×5 mL). The organic layer was separated, dried (MgSO4), filtered, and concentrated in vacuo. The residue obtained was purified by reverse phase chromatography (Biotage SP4, C-18 25M+, 40-95% CH3CN/water, 24 CV) to provide (R)-tert-butyl 4-(3-(tert-butoxycarbonylamino)piperidin-1-yl)-3-(cyclopropanecarboxamido)-5-methyl-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (86 mg, 55% yield) as a solid. LCMS (APCI+) m/z 514.1 (M+H)+.
