Abstract
A process for preparing compounds of the general formula: and acid addition salts thereof wherein: R1 is an alkyl radical possessing from 2 to 2 carbon atoms and carrying a hydroxyl group on at least one carbon atom other than that adjacent to the nitrogen atom; R2 is a hydrogen or an alkyl radical having one to four carbon atoms or an alkyl radical possessing from two to four carbon atoms and carrying a hydroxyl group on at least one carbon atom other than the one adjacent to the carbon atom. Nitrogen atom; W is a polymethylene chain - (ch2)n - where n is an integer from 2 to 10 or is a group -ch2 -m-ch2 where m is an aliphatic chain of 2 to 8 carbon atoms, at least one double or triple bond in which (in the case of more than one unsaturated bond) no there are two adjacent unsaturated bonds comprising the reaction of a disubstituted aliphatic compound in α: ω of the formula x - w - x with a disubstituted benzene of the formula: wherein x and y represent groups capable of reacting with each other to form an etheric bond and z is the desired group - nr1 R2 (in which the latter is a tertiary aminic group where R2 is hydrogen is a group -nr3 R1 in which R3 is a protective group) and the elimination of said protective group.
