(1S,3R)—N1-[5-fluoro-2-[5-fluoro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]cyclohexane-1,3-diamine, 44e, (2.3 g, 4.6 mmol) was dissolved in DMF (50 mL) and treated with morpholine-4-carbonyl chloride (2.1 g, 13.8 mmol) and DIPEA (4.2 g, 5.6 mL, 32.3 mmol). After one hour, the resulting solution was diluted with water (400 mL) and stirred for an additional two hours. The resulting precipitate was collected by filtration, washed with water (3×50 mL) and dried to provide the crude product. This material was purified by flash chromatography on a 40 g column using EtOAc/DCM 20-100%, to provide 2.0 g of 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 as a white solid.
