Reaction Steps

A mixture of N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (180 mg, 0.537 mmol, Example 1, Step I), tert-butyl hexahydropyrrolo[3,4-b]pyrrole-1(2H)-carboxylate hydrochloride (334 mg, 1.34 mmol), and DIEA (0.234 mL, 1.34 mmol) in n-BuOH (2 mL) was stirred at 140° C. for 5 hours in a sealed tube. The reaction was then cooled to room temperature and concentrated in vacuo. The residue obtained was purified by reverse phase HPLC (Gilson) to provide tert-butyl 5-(5-bromo-3-(nicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)hexahydropyrrolo[3,4-b]pyrrole-1(2H)-carboxylate (50 mg, 18% yield).
