Abstract
Improvements introduced in the object of the main patent no. 201,959, on "procedure for the preparation of 1,4-aralcohil-piperacinas", characterized in that they consist of reacting on a 1-aralcohil-piperazine a halide of another aralcohilo, which involves the formation of an intermediate compound which is obtained by reaction between an r- (cyclic group substituent) piperazine and an r '(substituent aliphatic group), which possesses an aldehydic 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 methods of preparation which can be used, provided that they consist of reacting a 1-aralcohyl-piperazine with an aldehyde of another aralcohyl, the reaction product being subjected to hydrogenation.
