Versuchsvorschrift
To a solution of 5-(3,4,5-trimethoxy-phenyl)-1H-pyrrolo[2,3-b]pyridine (510 mg, 1.79 mmol) in acetone (100 ml) was added N-iodosuccinimide (444 mg, 1.97 mmol) under stirring. After 1 hr the mixture was evaporated and purified by silica gel chromatography using 0-2% MeOH:DCM to give the title compound (870 mg, 118%). MS ESI (m/z): 411.1 (M+1)+, calc. 410.
