General description
1,2,3-Benzotriazin-4(3H)-one is an 1,2,3-benzotriazine derivative. 1,2,3-Benzotriazin-4(3H)-one undergoes thermal condensation with α-amino acids to yield 3H-1,4-benzodiazepin-(1H,4H)-2,5-diones. 1,2,3-benzotriazin-4(3H)-one on thermolysis yields quinazolino[3,2-c][1,2,3]benzotriazin-8-one.

The 5-HT1A receptor is a pharmacologically well characterized serotonin receptor subtype and it has long been investigated because of its involvement in several physiopathological mechanisms and treatment of neurological diseases like ansia and depression. Serotonin (5-HT) also shows many non-neural
