Potential neuroleptics of the orthopramide series; Synthesis of N-(3-(tert.amino)propyl)-5-sulfamoyl-2-methoxybenzamides

Abstract
Heating ethyl 5-sulfamoyl-2-methoxybenzoate with a series of twelve 3-(tert.amino)propylamines (IIIa-IIIl) afforded the title compounds IIa-IIl which were transformed to salts and subjected to pharmacological screening as potential neuroleptics of the sulpiride series. Only compounds IId (hydrogen oxalate, VUFB-15 453) and IIg (methanesulfonate, VUFB-15 397) showed indications of the desired psychotropic activity.
