ResumoAbstract The reaction of various heteroarylamines with ethyl 2‐benzoyl‐2‐bromoacetate was used to obtain some imidazo[1,2‐ a ]pyridines, imidazo[1,2‐ a ]pyrimidines, imidazo[2,1‐ b ]thiazoles and imidazo[2,1‐ b ]benzothiazoles characterized by the presence of a phenyl moiety on the imidazole ring. In the case of thiazole and benzothiazole derivatives, unexpected by‐products were isolated and their structures elucidated.
