Procedure

A mixture of 5.2 parts of 2-ethyl-1-(4-methoxyphenyl)-1H-imidazole and 75 parts of hydrobromic acid solution 48% in glacial acetic acid is stirred and refluxed overnight. The solvent is evaporated and the residue is triturated in 2-propanone. The product is filtered off and dried, yielding 6.1 parts (100%) of 4-(2-ethyl-1H-imidazol-1-yl)phenol monohydrobromide.
