Vorschrift

To a solution of 6-[[5-fluoro-2-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl]amino]norbornane-2-carboxylic acid, 72j, (0.030 g, 0.078 mmol) in THF (0.375 mL) was added triethylamine (0.032 mL, 0.234 mmol) and (azido(phenoxy)phosphoryl)oxybenzene (0.018 mL, 0.085 mmol). The reaction mixture was heated to 95° C. for 2.5 hours, cooled down to 5° C., and treated with pyrrolidine (0.010 mL, 0.117 mmol). The reaction was stirred for 3 days at room temperature. The reaction mixture was injected directly into a preparatory HPLC system for purification to provide the product as a racemic mixture. The single enantiomers were obtained by separation using SFC chiral purification to afford 5.7 mg of the desired product as well as 1.4 mg of the enantiomer.
