Procedure

5-cyano-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-2-yl diethyl phosphate (200 mg, 0.3359 mmol) was treated with a solution of (R)-tert-butyl 4-(1-aminoethyl)piperidine-1-carboxylate (76.70 mg, 0.3359 mmol) in THF (2 mL), and diisopropylethylamine (70.22 μL, 0.4031 mmol). The reaction mixture was stirred at room temperature for 24 hours. The crude mixture was diluted with ethyl acetate and washed with aqueous NaHCO3. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified on silica gel by flash column chromatography to afford the title compound as a colourless glass (188 mg, 84% yield).
