[origin: WO2007104872A1] ABSTRACT. PROCESS FOR PREPARING [2-(2,3-DIHYDROBENZOFURAN- OR BENZOFURAN-7-YLOXY)ETHYL]-(3-CYCLOPENT-1-YLBENZYL)AMINE DERIVATIVES AND SYNTHESIS INTERMEDIATE The invention relates to a process for preparing compounds of general formula (see "abstract" paper version) in which: - (a) is a single or double bond; - W is a CH, CH<SUB>2</SUB>, CHCH<SUB>3</SUB>, CCH<SUB>3</SUB> or C(CH<SUB>3</SUB>)<SUB>2</SUB> group or a C(CH<SUB>2</SUB>)<SUB>2</SUB> group (i.e. a carbon atom bearing two methylene groups linked to one another so as to form a spirocyclopropane unit), with the proviso, however, that, when (a) is a double bond, then W is exclusively a CH or CCH<SUB>3</SUB> group and that, when (a) is a single bond, then W is exclusively a CH<SUB>2</SUB>, CHCH<SUB>3</SUB>, C(CH<SUB>3</SUB>)<SUB>2</SUB> or C(CH<SUB>2</SUB>)<SUB>2</SUB> group.
