6-Chloro-7-iodo-7-deazapurine is used as pharmaceutical intermediate.

Definition

4-Chloro-5-iodo-7H-pyrrol[2,3-d]pyrimidine, also known as 6-Chloro-7-iodo-7-deazapurine or 4-Chloro-5-iodo-1H-pyrrolo[2,3-d]pyrimidine, is a white solid that can be obtained by iodine reaction of 4-chloro-7h-pyrrole [2,3-d] pyrimidine with NIS.

Synthesis

4-chloro-7h-pyrrole [2,3-d] pyrimidine (8.0 g, 52.32 mmol, 1.0 eq) was dissolved in DMF(40 mL) and NIS(15.7g, 57.55 mmol, 1.1eq) was added at 0℃. After stirring at room temperature overnight, 200 mL of saturated Na2S2O3 solution was added. The mixture was filtered, washed with water three times, and vacuum drying, to obtain 4-Chloro-5-iodo-7H-pyrrol[2,3-d]pyrimidine.
