title: 2-Benzazepines. 2. Thiazolo[5,4-d][2]benzazepines.
abstract: As part of a program in the area of annelated 2-benzazepines, several thiazolo[5,4-d))[2]benzazepines were prepared. Treatment of the bromo ketones 7-9 with various thio amides gave the thiazoles 10-15, which when treated with methylamine gave the title compounds. The preliminary pharmacology of these compounds showed that they had central nervous system activity similar to the 1,4-benzodiazepines, such as diazepam. The thiazolo[5,4-d][2]benzazepines were also found to bind to the benzodiazepine-receptor complex, indicating that their pharmacological actions are probably related to the 1,4-benzodiazepines.
