New 1 - angular clamp on 3 - (3,4,5 - trim ethoxy phenoxy) - 2 - hydroxypropyl bracket to - 4 - - - aryl piperazine derivatives and process for their preparation

摘要

The novel compounds correspond to the formula I, in which the substituents have the meaning given in Patent Claim 1. These compounds are prepared by reaction of a compound of the formula II with a compound of the formula III, Y and Z in each case being different and either denoting hydrogen or the group -CH2-CH(OR1)-CH2-V and V being chlorine, bromine or iodine, or, if R1 is hydrogen, can also form the ethylene oxide ring together with this hydroxyl group. If appropriate, one or two nitro groups in a compound of the formula I obtained can be reduced to amino groups and/or the compounds obtained can be acylated with an acid or an acid derivative corresponding to the radical R1. The compounds obtained can be converted into their acid addition salts. The novel compounds are pharmacodynamically active and are suitable as an active component in medicaments. IMAGE
