Novel 8-chloro-6-(2-fluorophenyl)-1-(aryl)-4H-[1, 2, 4] triazolo [4, 3-a][1, 4] benzodiazepines (5a–f) were prepared by treating 7-chloro-5-(2-fluorophenyl)-1, 3-dihydro-2H-1, 4- benzodiazepine-2-thione with various aromatic acid hydrazides. The newly prepared compounds were characterized by spectral analysis. Compounds were tested for anticonvulsant activity. Four of the tested compounds such as 5a, 5d, 5e and 5f exhibited ...
