Microwave-assisted Gewald Synthesis of 2-Aminothiophenes Using Functional Ionic Liquid as Soluble Support

A microwave-assisted liquid-phase Gewald synthesis of 2-aminothiophenes was developed using task-specific ionic liquid- [2-hydemim][BF 4 ] as soluble support. This new synthetic method is simple and efficient, and the products are obtained in good to excellent yields with high purities, without the need for chromatographic purification.
