Process for the preparation of benzofuran derivatives

摘要

Novel benzofuran derivatives of the formula (I) given in Patent Claim 1 are obtained as such or in the form of the acid addition salts by reaction of a corresponding benzofuran derivative of the formula (V) given in Patent Claim 1 with an appropriate primary amine of the formula (VI), optionally with subsequent conversion into the acid addition salt. The compounds (I) and their pharmaceutically acceptable acid addition salts are utilisable as medicaments, e.g. for the treatment of the circulation or of the peripheral nervous system. <IMAGE>
