Synthesis and biological activity of 5-phenyl-1,3,4-benzotriazepines. 13. Preparation of 2-alkylamino-5-phenyl-1,3,4-benzotriazepines as 2-thioxo-analogs and amines in the presence of heavy metal compounds
The S-N-exchange at 2-thioxo-5-phenyl-1,3,4-benzotriazepines by alkylamines to obtain the corresponding amino-heterocycles is successful if the starting compounds react at room temperature in the presence of heavy metal compounds. Convenient conditions ar
