Abstract: 
Different Lewis acids were screened to catalyze the reaction of 2-amino-thiophene-3-carboxylate, orthoformate and aryl amine to form 2-substituted thieno [2, 3-d] pyrimidin-4 (3H) -one. Zn (OAc)2 was demonstrated to efficiently catalyze the reaction. 20 substituted thieno [2, 3-d] pyrimidines were synthesized by adding 0.5% mol Zn (OAc)2 as catalyst under microwave irradiation.
