What are the synthesis methods of 2-iodobenzonitrile?

2-Iodobenzonitrile is also an important compound in organic synthesis. Its synthesis methods have been various.
One is to use 2-aminobenzonitrile as the starting material, and to prepare it through the steps of diazotization and iodine replacement. First, 2-aminobenzonitrile is combined with an appropriate amount of sodium nitrite and acid in a low temperature environment, and the reaction of diazotization is carried out to form diazonitrile salts. Then, potassium iodide or other iodine sources are added, so that the diazonitrile is replaced by iodine atoms, and then 2-iodobenzonitrile is obtained. The reaction conditions are relatively mild, but the stability of diazonitrile salts is not good. Careful should be taken during operation to prevent its decomposition.
