Abstract

Abstract 4(3 H )‐Quinazolinones were synthesized in high yields by one‐pot three‐component condensation of anthranilic acid, carboxylic acid and aniline in the presence of ionic liquid such as 1‐ n ‐butyl‐3‐methylimidazolium tetrafluoroborate (BMImBF 4 ) as catalyst under solvent free and neutral conditions.
