Versuchsvorschrift

To a solution of 22 (0.35 g) and acetone (20 mL) of acetone was added in one portion N-iodosuccinimide (0.44 g). The mixture was stirred at RT for 30 min and then concentrated to afford 0.8 g of crude material. The crude product was purified by SiO2 chromatography eluting with and EtOH/EtOAc gradient (1 to 15% over 15 minutes) to afford 0.36 g of pure 7-iodo-2-(pyridin-4-yl)-5H-pyrrolo[2,3-b]pyrazine (24).
