Abstract
Procedure for obtaining 2-piperidi-noalkyl- (1-benzofurans or 1,4-benzodioxanes) of general formula I **(See formula)** where Ph means a 1,2-phenylene residue, which is optionally substituted by 1 to 3 same or different substituents, selected from lower alkyl, hydroxy, mercapto, lower alkoxy, lower alkylenedioxy, benzyloxy, lower alkylthio, halogen, trifluoromethyl, nitro or amino, x means oxygen or sulfur, m is the integer 0 or 1 and n is 1 to 4, each of the symbols p and q represent an integer from 1 to 3, where (p + q) is the number 4, each of the symbols R1 and R2 means hydrogen, lower alkyl or HPh, R3 means hydrogen, hydroxy, lower alkoxy, lower or higher alkanoyloxy, R4 means lower alkyl, HPh-lower alkyl, HPh or naphthyl, which may be substituted as Ph, furyl, thienyl, pyridyl, benzofuryl, benzothienyl, quinolyl or isoquinolyl, the heterocyclic moieties of which are optionally substituted as Ph, as well as the acid addition salts, especially the therapeutically usable acid addition salts is one of these compounds, characterized in that a compound of general formula III **(See formula)** where A signifies a group of formula (see formula) or (see formula), where Y'signifies an esterified hydroxy group, capable of reaction, R5 signifies hydrogen or R1 and R2 together form another bond C, C, R'4 signifies R4 or HPh-lower alkanoyl each of the symbols r and s means the integer 0 or 2, where (r + s) is the number 2 or 4, if desired, a free compound obtained is reduced to an addition salt. of acid or an acid addition salt obtained in the free compound or in another acid addition salt, and/or, if desired, a mixture of isomers or racemates obtained is separated into the different isomers or racemates, and/or, if desired, the racemates obtained are dissociated in the optical antipodes.
