Tert-butyl (3-methylpiperidin-3-yl)carbamate → N-(4-(3-Amino-3-methylpiperidin-1-yl)-5-bromo-1H-pyrrolo [2,3-b]pyridin-3-yl)-2-methoxyacetamide

Reaction Steps

N-(5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxyacetamide (100 mg, 0.331 mmol, Example 31, Step A) and tert-butyl 3-methylpiperidin-3-ylcarbamate (213 mg, 0.993 mmol) in n-BuOH (4 mL) were heated to 160° C. for 48 hours in a sealed tube. After concentration, the residue was purified by C-18 reverse phase flash chromatography (Biotage SP4 unit, C-18 25M column, 10-90% CH3CN/water gradient; 30 CV) to yield N-(4-(3-amino-3-methylpiperidin-1-yl)-5-bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxyacetamide (65 mg, 49% yield) as a solid and tert-butyl 1-(5-bromo-3-(2-methoxyacetamido)-1H-pyrrolo[2,3-b]pyridin-4-yl)-3-methylpiperidin-3-ylcarbamate (32 mg, 19% yield) as an oil.
