Versuchsvorschrift
The amino-benzotriazine N-oxide (16) is diazotized with NaNO2/HCl and the intermediate diazonium salt (not shown) is hydrolysed to form the hydroxybenzotriazine N-oxide compound (17). Reaction of the hydroxybenzotriazine N-oxide compound (17) with phosphorus oxychloride in the presence of a non-interfering base such as N,N-dimethylaniline gives the chlorobenzotriazine N-oxide compound (18). The chlorination reaction is typically carried out with heating, for example at reflux temperatures.
