摘要：

Microwave-assisted synthesis of new 2-arylpyrimido[4',5':4,5]thiazolo[3,2-a]benzimidazol-4(3H)-ones from 3-aminothiazolo[3,2-a]benzimidazol-2-carboxamide and aroyl halides in solvent-free condition is described. In comparison with classical conditions the reactions are faster and the yields are higher under microwave irradiation. (c) 2007 A. Davoodnia.
