Reaction Steps

4,4,5,5-Tetramethyl-2-(prop-1-en-2-yl)-1,3,2-dioxaborolane (436 mg, 2.59 mmol), PS-tetrakis (triphenylphosphine) palladium (786 mg, 0.0864 mmol, 0.10 mmol/1 g) and 2N sodium carbonate (1296 μL, 2.59 mmol) were added to (R)-tert-butyl 5-bromo-4-(3-(tert-butoxycarbonylamino)piperidin-1-yl)-3-(cyclopropanecarboxamido)-1H-pyrrolo[2,3-b]pyridine-1-carboxylate (500 mg, 0.864 mmol; Example 107, Step A) in degassed dioxane (1 mL). The reaction was heated to 120° C. for an hour under microwave irradiation. The reaction was then heated to 150° C. for 30 minutes. The reaction was filtered and extracted with DCM. The organic layer was concentrated, and the resulting residue was purified by reverse phase chromatography (Gilson, C-18, 5-95% CH3CN/water) to yield (R)-tert-butyl 1-(3-(cyclopropanecarboxamido)-5-(prop-1-en-2-yl)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (236 mg, 62% yield).
