tert-Butyl methyl((3R)-piperidin-3-yl)carbamate → (R)-tert-butyl 1-(5-bromo-3-(nicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate

Reaction Conditions

Reaction Steps

(R)-tert-Butyl methyl(piperidin-3-yl)carbamate (384 mg, 1.79 mmol) was added to N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (200 mg, 0.597 mmol, Example 1, Step I) in n-BuOH (3 mL), and the reaction was stirred at 160° C. for 24 hours in a sealed tube. The reaction was concentrated to dryness. The residue was then purified by chromatography (Biotage SP4, C-18 25M+ column, 10-90% CH3CN/water gradient, 30 CV) to yield (R)-tert-butyl 1-(5-bromo-3-(nicotinamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-yl(methyl)carbamate as a solid.
