Versuchsvorschrift

A solution of 4-bromo-7-methoxy-1-tosyl-1H-pyrrolo[2,3-c]pyridine (12.4 g, 32.6 mmol) in dioxane (140 mL) was stirred at room temperature. To this solution was added 4M HCl in dioxane (140 mL). The reaction mixture was stirred at 40° C. for 16 hours. The reaction mixture was cooled to room temperature and concentrated. The residue was triturated with diethyl ether, filtered, and rinsed with additional diethyl ether and dried to provide 4-bromo-1-tosyl-1H-pyrrolo[2,3-c]pyridin-7(6H)-one (11.23 g, 30.6 mmol, 94% yield) as a beige solid.
