Innovative Protocol for the Synthesis of Acridine Derivatives using Ionic Liquid

Innovative protocol for the synthesis of acridine derivatives by reaction of dimedone, aromatic aldehyde and ammonium acetate is developed using ionic liquid 1-butyl-3-methylimidazolium perchlorate ( [Bmim]ClO4). The method provides several advantages such as simple work up, environmental friendliness and excellent yields in short reaction time. The ionic liquid [Bmim]ClO4 used was recovered and reused for three times.
