Extensive work from Fourneau's Laboratory2 has indicated that some relatively simple aminoethers (type F929, F1379, F1464) 3 and diamines: t\-pe Flt5il, FLG91, F1'709, RP 2339, RP 2325) 4 possesset. antihistaniinic activity. Since tertiary amines of this group containing heterocyclic radicals had so far not been studied, we have synthesized a number of asymmetricallysubstituted ethylenediarnines of the general type
