Reaction Steps
Benzyl 3-(5-cyano-2-(methylsulfonyl)pyrimidin-4-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-ylcarbamate (0.826 g, 1.372 mmol) in THF (30 mL) was treated with isopropylamine (0.234 mL, 2.744 mmol, 2.0 Eq) and DIPEA (0.478 mL, 2.744mmol, 2.0 Eq) and allowed to heat at reflux for I hour. The mixture was concentrated in vacuo and purified by column chromatography (ISCO Companion™, 40 g column, 0-100% EtOAc/Petroleum ether) to give 0.651 g (82%) of the title compound.
