실험 절차

A mixture of 8.1 g (49 mmol) 1,2,4-benzotriazine-3-amine 1-oxide, 8.1 g sodium dithionite and 800 ml 70 percent ethanol is heated under reflux for 1 h. One filters hot, evaporates the filtrate, washes the residue with water and dries. There remain 7.0 g 1,2,4-benzotriazine-3-amine (98% of theory) of the m.p. 208°-210° C.
