N-[(1R,3S)-3-[[5-fluoro-2-[5-fluoro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]cyclohexyl]morpholine-4-carboxamide, 44f, (2.0 g, 3.2 mmol) was suspended in methanol (50 mL) and treated with 25% sodium methoxide in methanol (19.9 mL, 92.3 mmol). After stirring for 1 hour, the solvent was evaporated under reduced pressure, and the residue was partitioned between water (100 mL) and ethyl acetate (100 mL). The organic layer was collected, dried on Na2SO4 and concentrated to provide the crude product as a yellow solid. This material was purified by silica gel chromatography on a 40 g column, using DCM/MeOH 1-6%. The purified fractions were treated with 2N HCl in ether and concentrated to provide 1.5 g of N-[(1R,3S)-3-[[5-fluoro-2-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl]amino]cyclohexyl]-morpholine-4-carboxamide as a white solid.
