Abstract
Improvements introduced in the object of the main patent no. 201,959, on "process for the preparation of 1,4-aralcohil-piperacines, characterized in that they consist of reacting on a 1-aralcohyl, piperazine a halide of another aralcohyl which involves the formation of an intermediate compound that is obtained by reaction between an r- (cyclic group substituent) piperazine and an r "(substituent aliphatic group), which possesses an aldehyde function and the reduction of this intermediate compound by means of hydrogen under pressure in the presence of a catalyst, it being also possible to use other suitable preparation methods, provided that they consist of reacting a 1-aralcohyl-piperazine with an aldehyde of another aralcohyl, the reaction product being subjected to hydrogenation.
