Participants

Reaction Steps

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 methyl chloroformate (0.009 g, 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, 440.
