Benzazolo [2,1-b] quinazolinones and triazolo[2,1-b] quinazolinones were synthesized in high yields by the condensation reaction of an aldehyde and a cyclic beta-diketone with 2-aminobenzimidazole, 2-aminobenzothiazole or 1, 2, 4-triazole derivatives in 1-butyl-3 methylimidazolium bromide as an ionic liquid under classic heating conditions within 5-60 minutes.
