Process for the preparation of 4(3H)-quinazolinones |
| abstract |
A new process for the preparation of 3-(1H-tetrazol-5-yl)-4(3H)-quinazolinones from anthranilic acid derivatives is described herein. Additional reactants used in the process are 4-aminotetrazole and a trialkoxymethane or the reaction can be carried out using the imidic ester obtained from these two compounds. |
