Abstract

Process for the preparation of methyl piperazine derivatives of the general formula i ** (see formula) ** Wherein x means a sulfur or oxygen atom or a methylene group and r means a hydrogen or halogen atom, an alkyl radical, alkoxy, an alkylthio group, an alkyl silylene or an alkanesulphonyl group having 1 to 5 carbon atoms, or a benzyloxy or dimethylsulfamyl group, and their salts, by reduction of ethoxycarbonylpiperazine derivatives of the general formula xii ** (see formula) ** Wherein x and r mean the same as in formula i, with complex hydrides and optionally by neutralization of the resulting bases of the general formula i with organic or inorganic acids with formation of corresponding salts, characterized in that the reduction is carried out using sodium hydride-di (2-methoxyethoxy) -aluminum as a reducing agent.
