Abstract
The invention comprises compounds of the formula <FORM:1022031/C2/1> wherein R represents a saturated or unsaturated straight or branched chain C2- 5 alkyl group which may be substituted by a basic nitrogen-containing group of R1 and R2 represent identical or different straight or branched chain saturated alkyl groups, or the groups R1 and R2, together with the nitrogen atom to which they are attached, form a heterocyclic group which may be interrupted by a further hetero atom, and n = 2 or 3. The compounds are prepared by reacting a 3,5-dimethoxy-4-alkoxy-benzoic acid or a reactive derivative thereof, with a basic alcohol of the formula <FORM:1022031/C2/2> or with a reactive derivative thereof. 3,5 - Dimethoxy - 4 - alkoxy - benzoic acid chlorides are prepared by alkylating a 3,5-dimethoxy-4-hydroxy-benzoic acid or an ester thereof to form a 3,5-dimethoxy-4-alkoxy-benzoic acid or an ester thereof, followed, if necessary by hydrolysis of the ester to form the free acid, and reacting the free acid with thionyl chloride to form the acid chloride.
