ABSTRACT:
The present invention provides a method for producing a 4-nitroimidazole compound represented by general formula (1) at high yield and at high purity by a safe method causing few dangers such as explosion. The production method of the present invention comprises iodinating a 4-nitroimidazole compound represented by general formula (2): wherein each of X1and X2represents a chlorine atom or bromine atom, and then reducing the obtained 5-iodo-4-nitroimidazole compound represented by general formula (3): wherein X2is the same as defined above.
