Reaction Steps

To a racemic solution of methyl 3-((5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl)amino)-3-(1-methylcyclobutyl)propanoate, 119a, (3.3 g, 5.9 mmol) in acetonitrile (25 mL) was added HCl (26 mL of 4N solution in dioxane). The reaction mixture was heated to 65° C. for 4 hours. The solution was cooled to room temperature and the solvents were removed under reduced pressure. The mixture was flushed with acetonitrile after which aqueous sodium bicarbonate and ethyl acetate were added. The phases were separated and the aqueous layer washed with ethyl acetate. The combined organic phases were dried with Na2SO4, filtered and concentrated in vacuo. The resulting residue was purified via silica gel chromatography (EtOAc/Hexanes) to afford the desired product: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, RT=2.34 minutes (M+H) 403.11.
