To a suspension of 2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine (2.0 g, 10.6 mmol) in CH2Cl2 (32 mL) was added N-iodosuccinimide (NIS) (2.4 g, 10.6 mmol) at room temperature. After stirring for 1 h, the resulting precipitates were collected by filtration to give 2,4-dichloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (1.8 g).
