Procedure

A 250 mL round bottom flask was charged with 5-chloro-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (1.6 g, 8.62 mmol; Example 8, Step D), (R)-tert-butyl piperidin-3-ylcarbamate (5.18 g, 25.9 mmol), N-ethyl-N-isopropylpropan-2-amine (4.51 mL, 25.9 mmol), and NMP (15.5 mL). Then N2 was bubbled through the mixture for 5 minutes and stirred at 120° C. under N2 atmosphere for 16 hours to provide the crude (R)-tert-butyl 1-(3-amino-5-chloro-1H-pyrrolo[2,3-b]pyridin-4-yl)piperidin-3-ylcarbamate. LCMS (APCI+) m/z 366.1 (M+H)+.
