Abstract

Amino - ethers of the general formula A-O-CHn2nNRR1, wherein A represents the benzohydryl or 9-fluoryl radical or the radical <FORM:0646048/IV (b)/1> in which X is a sulphur or oxygen atom or the methylene group, n is 2 or 3, and R and R1 each represent an unsubstituted alkyl group containing not more than 4 carbon atoms, are prepared by heating the corresponding polynuclear alcohol with the appropriate tertiary alkylaminoalkyl halide or a salt thereof, in the presence of caustic alkali, e.g. in the presence of dry, powdered sodium hydroxide. Suitable alkylaminoalkyl halides mentioned are the dimethylamino-, diethylamino-, and dibutylamino-ethyl and propyl chlorides. A number of specific compounds are mentioned. The product may be converted to a salt.
