Imidazopyridines in acetic acid solution are readily nitrated by nitric acid-sulphuric acid, although in some instances treatment of the base hydrogensulphate with nitric acid-acetic acid is preferred.Nitration occurs most readily in the 1-position, but 3-nitration occurs if the 1-position is already substituted.
