| Abstract: | The reaction of anthranilic acid hydrazide with diethyl oxalate under microwave irradiation was accompanied by decarboxylation with formation of 3-amino-3,4-dihydroquinazolin-4-one, and acylation of the latter with succinic anhydride gave N-(4-oxo-3,4-dihydroquinazolin-3-yl)siccinimide which was converted into various N-(4-oxo-3,4-dihydroquinazolin-3-yl)succinamic acid derivatives. |
