Reaction Steps

To a stirred suspension of 2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-N-[(3S)-pyrrolidin-3-yl]pyrimidin-4-amine hydrochloride, 7c, (0.05 g, 0.10 mmol) in THF (1 mL) was added iPr2NEt (0.10 mL, 0.57 mmol) followed by methanesulfonyl chloride (0.04 mL, 0.57 mmol). The resulting homogenous light yellow mixture was heated at 50° C. for one hour at which time LCMS showed complete reaction. Morpholine (0.20 mL) was added and the solution evaporated to dryness. The resulting residue was dissolved in methanol (2 mL) then treated with 25% sodium methoxide/methanol (0.5 mL) and heated at 60° C. in sealed tube until LCMS showed reaction was complete. The resulting solution was quenched with aqueous saturated NH4Cl (0.5 mL) then evaporated to dryness. The residue was dissolved in DMSO and purified by reverse phase HPLC (ammonium formate buffer) to afford 15.8 mg (37% yield) of 398, as a solid.
