Participants

Reaction Conditions

Reaction Steps

To a stirred solution of 4-nitro-1H-pyrrolo[2,3-b]pyridine (4.5 g, 27.6 mmol) in DCM (180 mL) was added NIS (6.83 g, 30.3 mmol) over 30 mins at 0° C. The resulting mixture was stirred at 0° C. for another 1 hour. The reaction mixture was concentrated. The residue was suspended in DCM (ca. 25 mL), the solid was filtered and dried in a vacuum oven to give the title compound (8.51 g). LCMS (A): m/z (M+H)+ 290, C7H4IN3O2 requires 289 (acidic).
