Abstract

In this paper, a new and efficient method was developed to prepare 2-aminothiophene derivatives through improved Gewald reaction. Thirty-one final products were synthesized under microwave radiation for 30 min with 57%-95% isolated yield. All the products were could be used as building blocks in drug discovery.
