F]-Fluoromisonidazole is the most widely used radiopharmaceutical for imaging hypoxia in tumors.
The precursor for [ 18 F]-fluoromisonidazole was prepared from 1,3-dibromo-2propanol in 5 steps from available materials and straightforward purification steps. The overall yield for this synthesis was 18%.
