A number of 3-amino-2,4(1H,3H)-quinazolinediones were synthesized from o-aminobenzoylhydrazines and ethyl chloroformate in pyridine or from 2-methoxycarbonylphenyl isocyanate and 1,1-disubstituted hydrazines. Four of the ten compounds screened exhibited anticonvulsant activity in mice.

4-dihydro-2(1H)-quinazolinones have been synthesized from ethyl chloroformate and o-aminobenzylhydrazines. The latter compounds were obtained from the metal hydride reduction of either o-aminobenzhydrazides or o-acylaniline hydrazones. All compounds were evaluated in mice in the maximal electroshock (MES) seizure and pentylenetetrazole (sc Met) seizure threshold tests for anticonvulsant activity and in
