N-Iodosuccinimide → 2,4-Dichloro-5-iodo-7H-pyrrolo(2,3-d)pyrimidine

Participants

Reaction Steps

To a suspension of 2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine (3.00 g, 16.0 mmol) in CH2Cl2 (30 mL), N-iodosuccinimide (3.60 g, 16.0 mmol) was added. It was stirred at room temperature for 20 h. The fine precipitate was collected, dried on vacuum to give 2,4-dichloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (2.80 g). MS 314.1 and 316.1 (M+H)
