Microwave irradiation in solvent-free conditions: Preparation of 2-substituted 4(3<i>H</i>)-quinazolinones by heterocyclisation of 2- aminobenzamide with carboxylic acids
679-681A simple and
fast preparation of 2-substituted-4(3H)quinazolinones in high yields has been
developed by microwave induced heterocyclisation of 2-aminobenzamide with
carboxylic
acids in
solvent-free conditions. In comparison, the reactions are 40-80 times faster
under microwave irradiation and the yields are much higher than conventional
heating
