A compound of the formula ##EQU1## or an acid addition salt thereof wherein R.sup.1 and R.sup.2 are the same or different and each is a phenyl or thien-2-yl group optionally substituted in one or more positions by a substituent selected from the class consisting of halogen, lower alkyl, lower alkoxy, hydroxy, lower alkylthio, phenyl, phenoxy, phenyl-(lower-alkyl) and phenyl-(lower-alkoxy), each of the said phenyl, phenoxy, phenyl-(lower-alkyl) and phenyl-(lower-alkoxy) substituent groups being optionally substituted in one or more positions by a member selected from the class consisting of halogen, lower alkyl, lower alkoxy, hydroxy, and lower alkylthio; A.sup.1 is a divalent straight or branched alkylene group containing from two to six carbon atoms and one or two divalent atoms which are each an oxygen or sulphur atom, provided that there are at least two carbon atoms between the divalent atom and the --NH-- group and between the two divalent atoms; and A.sup.2 is the methylene group --CH.sub.2 --.
式##EQU1##的化合物或其酸加合盐,其中R.sup.1和R.sup.2相同或不同,每个都是苯基或噻吩-2-基团,可以在一个或多个位置被来自卤素、低烷基、低烷氧基、羟基、低烷硫基、苯基、苯氧基、苯基-(低烷基)和苯基-(低烷氧基)的取代基中选择的取代基取代,所述的苯基、苯氧基、苯基-(低烷基)和苯基-(低烷氧基)取代基中的每一个可以在一个或多个位置被来自卤素、低烷基、低烷氧基、羟基和低烷硫基的取代基中选择的成员取代;A.sup.1是含有两至六个碳原子和一个或两个二价原子的直链或支链烷基基团,每个二价原子都是氧原子或硫原子,前提是二价原子和--NH--基团之间以及两个二价原子之间至少有两个碳原子;A.sup.2是亚甲基基团--CH.sub.2 --。
