Procedure

tert-Butyl N-[(1R,3S)-3-[[5-fluoro-2-[5-fluoro-1-(p-tolyl sulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]cyclohexyl]carbamate, 44d, (3.7 g, 6.2 mmol) was dissolved in dichloromethane (105 mL) and treated with trifluoroacetic acid (31 mL). After 5 minutes, the volatiles were evaporated under reduced pressure, and the resulting residue was treated with 1N NaOH (75 mL). The resulting precipitate was collected by filtration, washed with water (3×30 mL) and vacuum dried to provide 2.7 g of (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 as a white solid.
