Chemical structure of alprazolam
, a common triazolobenzodiazepine
Triazolobenzodiazepines are a class of benzodiazepine pharmaceutical drugs. Chemically, they differ from other benzodiazepines by having an additional fused triazole ring.
Synthesis of 1-methyltriazolobenzodiazepines (alprazolam type) is possible by heating 1,4-benzodiazepin-2-thiones with hydrazine and acetic acid in n-butanol under reflux.
