Reaction Steps

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (100 mg, 0.3 mmol, Example 1, Step I) in n-BuOH (3 mL) and tert-butyl azetidin-3-ylcarbamate (154 mg, 0.9 mmol) were heated to 110° C. in a sealed tube for 24 hours. After cooling down, the reaction was concentrated to dryness, and the residue purified by C-18 reverse phase flash chromatography (Biotage SP4 unit, C-18 25M column, 10-90% CH3CN/water gradient; 30 CV) to yield tert-butyl 1-(5-bromo-3-(nicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)azetidin-3-ylcarbamate (54 mg, 37% yield) as a solid.
