Abstract
Abstract N-Arylanilines, further substituted on nitrogen by aroyl, aralkanoyl or aralkyl groups, and wherein one of the aryl groups has a 3- or 4-(aminoalkoxy)substituent, having hypocholesteremic activity, are prepared by a series of O-alkylation, N-acylation or -alkylation, and reduction reactions starting from the appropriate hydroxydiarylamines or benzyl ethers thereof.
