Reaction Steps

To a solution of (1S,3R)—N1-[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]cyclohexane-1,3-diamine (0.06 g, 0.12 mmol) in CH2Cl2 (3 mL) was added 4-tert-butoxycarbonylmorpholine-2-carboxylic acid (40.4 mg, 0.17 mmol), EDC (0.03 g, 0.14 mmol), HOBt (0.02 g, 0.12 mmol) and iPr2NEt (0.06 g, 0.47 mmol), and the reaction mixture was stirred at room temperature overnight. The solvent was evaporated under reduced pressure, and the residue was dissolved in CH2Cl2 (2 mL) and TFA (2 mL) and allowed to stir at room temperature for 2 hours. The resulting solution was concentrated in vacuo, dissolved in THF (4 mL) and treated with 1N aqueous lithium hydroxide (3.0 mL, 3.0 mmol). The reaction mixture was heated in the microwave to 130° C. for 20 min. The solvent was evaporated under reduced pressure, and the residue was purified by HPLC, using 5-70% MeOH/H2O with 6 mM HCl over 15 minutes. The purified fractions were concentrated to provide the bis-hydrochloride of N-[(1R,3S)-3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]cyclohexyl]morpholine-2-carboxamide.
