Abstract
The invention refers to a novel process for the preparation of {2-[-(α-phenyl-p-chlorobenzyl)piperazin-1-yl]ethoxy}acetic acid, which comprises hydrolyzing an N,N-disubstituted {2-[-(α-phenyl-p-chlorobenzyl)piperazin-1-yl]ethoxy}acetamide, wherein said substituents are selected from alkyl groups having 1 to 4 carbon atoms optionally substituted by a phenyl group, alkenyl groups having 2 to 4 carbon atoms or cyclohexyl groups, or the substituents together with the adjacent nitrogen atom of the acetoamido group, form a morpholino group.
