A solution of N-((1R,3S)-3-(5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)cyclohexyl)pyrrolidine-1-carboxamide, 67f, (11.5 g, 19.3 mmol) in THF (150 mL) was added sodium methoxide (4.173 g, 19.31 mmol). After stirring the reaction mixture for 2 minutes, the mixture was poured into an aqueous saturated solution of NaHCO3. The organic phase was washed with brine, dried over MgSO4 and the solvent was removed under reduced pressure. The resulting residue was purified by silica gel chromatography (10% MeOH/CH2Cl2) to afford 6.5 g of the desired product. The product was converted to an HCl salt by dissolving in MeOH (100 mL) and adding 2.4 mL of 12M HCl solution at room temperature. The solution was stirred at for 1 hour and the HCl salt precipitated out and filtered to provide 7.05 g of the HCl salt.
