To a solution of (S)-2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-N-(piperidin-3-yl)pyrimidin-4-amine hydrochloride, 5b, (0.042 g, 0.100 mmol) in CH2Cl2 (1.4 mL) and DMF (0.3 mL) was added N,N-diisopropyl-N-ethylamine (0.300 mL, 1.720 mmol) followed by isocyanatopropane (0.120 mmol). The reaction mixture was stirred at room temperature for 17 hours. The mixture was concentrated in vacuo, dissolved in 1 mL of DMSO and purified by preparatory HPLC (0.1% ammonium formate-H2O/acetonitrile) to afford the desired product, 439.
