| titleOfInvention | PROCESS FOR THE PREPARATION OF METHYLPIPERAZINE DERIVATIVES. |
| abstract | In a method of preparing cpds. formula (I): (where Z is CH3, X is S, O or a methyl group and R is H or halogen, or an alkyl, alkoxyl, alkylthio-, alkyl-seleno- or alkanesulphonyl group with 1 to 5C or a benzyloxy- or dimethylsulphamyl group, and the salts thereof) by reducing ethoxycarbonyl-piperazine derivs. of formula (I; Z = COOC2H5) by means of complex hydrides and contingent neutralisation of the resulting bases of formula (I) with inorganic or organic acids to give corresponding salts, the reduction is carried out with sodium bis (2-methoxythyoxy) aluminium hydride as the reducing agent. |
