<b>Silica sulfuric acid promoted one-pot synthesis of benzo[4,5]imidazo[1,2-<i>a</i>]pyrimidine derivatives under solvent-free conditions</b>

A simple and efficient synthesis of benzo[4,5]imidazo[1,2-<i>α</i>]pyrimidine derivatives has been accomplished by the reaction of 2-aminobenzimidazole, aldehydes and β-dicarbonyl compounds under solvent-free conditions in the presence of silica sulfuric acid.
