Conditions

Temperature: 160 °C

Procedure

Potassium iodide (4.8 g) and 1-methyl-2-methylsulfonyl-5-nitroimidazole (5.0 g) were combined in N,N-dimethylformamide (30 ml) and the reaction mixture heated to 160° C. for 2 hours. Upon cooling, the reaction mixture was added to 150 ml of a water and ice mixture. The product precipitated and was filtered and dried affording 4.4 g of 1-methyl-2-methylsulfonyl-4-nitroimidazole.
