Compounds of the class of acetals of 6-phenyl-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carboxaldehyde and the 5-oxides and pharmaceutically acceptable acid addition salts thereof have valuable pharmacological properties, in particular anticonvulsant effectiveness. Further, they show central depressant and muscle-relaxing activity and are active ingredients for therapeutic preparations. Specific embodiments are 6-phenyl-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carboxaldehyde -diethylacetal, 6-(o-chlorophenyl)-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carb oxaldehyde-diethylacetal and 6-(o-fluorophenyl-8-chloro-4H-s-triazolo[4,3-a][1,4]benzodiazepine-1-carbo xaldehyde-diethylacetal.
