microwave-assisted green chemical synthesis of condensed 2-substituted-pyrimidin-4(3H)-ones 3, 4, and 5 involving the condensation of a variety of nitriles with o-aminoesters of thiophene , benzene , dimethoxybenzene and quinazolinone in the presence of catalytic amount of HCl alone or with the Lewis acid AlCl3 under solvent-free conditions, is described for the first time. This novel and clean one-pot methodology
