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, (0.04 g, 0.10 mmol) in CH2Cl2 (1.4 mL) and DMF (0.3 mL) was added N,N-diisopropyl-N-ethylamine (0.3 mL, 1.72 mmol), followed by 3-(ethyliminomethyleneamino)-N,N-dimethyl-propan-1-amine hydrochloride (0.02 g, 0.12 mmol), 1-hydroxybenzotriazole hydrate (0.02 g, 0.12 mmol) and 1-methylcyclopropane-1-carboxylic acid (0.01 g, 0.12 mmol). 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, 445.
