1-acylamino-2-benzimidazolinones. The latter compounds were obtained in two steps from o-nitro-β-acylphenylhydrazines. All of the 1-amino-2-benzimidazolinones exhibited activity in the standard anticonvulsant tests except for the 1-benzylamino compound. The most active compound was 1-ethylamino-2-benzimidazolinone which protected mice in the maximal electroshock seizure test at 30 mg/kg.
