Synthesis of perhydro-1,4-thiazepines, of expected pharmacological activity. Part III....

New esters, derivatives or the title aminoalcohol, were obtained by three classical methods in the reaction of 4-(2-hydroxyethyl)-perhydro-1,4-thiazepine (HEPT) with chlorides (method a), acid potassium salts (method b), and sodium HEPT salts with acid chlorides (method c). Compounds 3 and 5 have weak spasmolytic properties; 5 in a dose of approx. 50 mg/kg strongly depressed the central nervous system.
