참여 물질

반응 단계

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, 0.11 mmol) in CH2Cl2 (1.40 mL) and DMF (300μ was added N,N-diisopropyl-N-ethylamine (0.30 mL, 1.70 mmol) followed by cyclobutanecarbonyl chloride (0.01 g. 0.12 mmol). The reaction mixture was allowed to stir 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, 395.
