Abstract
Abstract A series of substituted amino ethyl meta benzoic acid amides and their salts are useful as spasmolytics, pschyotherapeutic agents and agents facilitating learning. These compounds may conveniently be prepared by hydrolysis of suitably substituted trifluoromethyl derivatives followed by amidification with a desired amine, or by a replacement reaction between a suitable ester and an appropriate amine, or by reaction of an activated form of the free acid and an appropriate amine.
