Reaction Steps

A solution of tert-butyl (3S)-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[5,4-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]pyrrolidine-1-carboxylate, 7b, (1.33 g, 2.27 mmol) in THF (25 mL) was treated with hydrogen chloride (12 mL of 4M solution in dioxane, 48.00 mmol) at room temperature. The reaction was then heated at 90° C. until LCMS showed reaction was complete. The mixture was concentrated to dryness then dried under vacuum to afford 1.04 g (88% yield) of 7c, as a tan solid.
