A novelmethodology for the synthesis of N-substituted-3-aryl-2-thioxotetrahydropyrimidin-4(1H)-one derivatives had been developed by the condensation of aryl isothiocyanates with β-amino esters using lithiumperchlorate as a catalyst and triethylamine as a base. This strategy not only overcomes the disadvantages of the reported methods but also provides high yield of the product in short span of time
