Reaction Steps

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-(4-methoxybenzyl)-1H-pyrazole-4-carboxamide (230 mg, 0.518 mmol) and (R)-tert-butyl piperidin-3-ylcarbamate (311 mg, 1.55 mmol) in n-BuOH (2.5 mL) was heated to 155° C. for 48 hours in a sealed tube. The reaction mixture was then cooled to room temperature and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC (Gilson) to provide (R)-tert-butyl 1-(5-bromo-3-(1-(4-methoxybenzyl)-1H-pyrazole-4-carboxamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate (60 mg, 18% yield).
