実験手順

8.5 g of 8-chloro-6-(2-fluorophenyl)-4H-s-triazolo[4,3-a][1]benzazepine are dissolved in 135 ml of chloroform and 3.3 ml of pyridine. 2.0 ml of bromine are added dropwise at room temperature while stirring. The mixture is then heated to 55°-60° for 50 minutes and evaporated in vacuo. The residue is chromatographed on 550 g of silica gel. By elution with chloroform which contains 0.3% or 0.4% methanol and crystallization of the obtained material from benzene there is obtained 1-bromo-8-chloro-6-(2-fluorophenyl)-4H-s-triazolo[4,3-a][1]benzazepine of melting point 222°.
