Versuchsvorschrift
A mixture of 4-bromo-1H-pyrrolo[2,3-b]pyridine (1.00 g, 5.08 mmol) and NBS (0.918 g, 5.16 mmol) in DCM (20.0 mL) was stirred at 0° C. for 1.5 hour. The resulting suspension was filtered, washed with DCM, residue collected, dried in a 50° C. oven overnight to afford the title compound (1.014 g). LCMS (A): m/z (M+H)+ 277, C7H4Br2N2 requires 276 (basic).
