Abstract
Process for obtaining piperazine compounds, especially for the preparation of N- (2-OR-2-Ph-ethyl) -N'-Ar-piperazines of the general formula ** (See formula) ** where Ph means a radical of (halogen) -phenyl or (trifluoromethyl) -phenyl, R low alkyl, R1 hydrogen or methyl and Ar phenyl, (lower alkyl) -phenyl, (lower alkoxy) -phenyl, (halogen) -phenyl or pyridyl, its N-oxides or quaternary compounds, characterized in that an N-Ar-piperazine of formula ** (See formula) ** where Ar and R1 have the meaning indicated above, or their salts, are reacted with a reactable ester of a 2-OR-2-Ph-ethanol of the formula ** (See formula) ** where R and Ph have the above meaning and Y means a reactably esterified hydroxyl group, or a 2-OR-2-Ph-ethylamine of formula ** (See formula) ** where Ph and R have the meaning indicated above, is reacted with a N, N-di- (hydroxyethyl) -N-Ar-amine twice reactably esterified, of formula ** (See formula) ** where Ar, R1 and Y have the meaning indicated above, or a N, N-di- (hydroxy-ethyl) -N- (2-OR-2-Ph-ethyl) -amine twice reactably esterified of formula ** (See formula) ** where Ph, R, R1, and Y have the meaning indicated above, is reacted with an amine of formula Ar-NH2, where Ar has the meaning indicated above, or in an N- (2-hydroxy-2-Ph-ethyl) ) -N'-Ar-piperazine of formula ** (See formula) ** where Ph, R and Ar have the meaning indicated above, the hydroxyl group is transformed into a lower alkoxy group, or into an N- (2-OR-2-Ph-acetyl) -N'-Ar-piperazine or an N- - (2-OR-2-Ph-ticacetyl) -N-Ar-piperazine of formula ** (See formula) ** where Ph, R, R1 and Ar have the meaning indicated above and X represents oxygen or a sulfur atom, the carbonyl or thiocarbonyl group is converted to the methylene group, or an N- (2-OR-2-Ph-ethyl) -N'-Ar-ethylenediamine of formula ** (See formula) ** where Ph, R, R1 and Ar have the above meaning, is reacted with a reactable diester of the ethylene glycol of formula Y-ch2-ch2-y XIV where Y has the meaning indicated above and, if desired, the salts obtained are transformed into the free compounds or other salts, and/or, if desired, the obtained compounds are transformed into their N-oxides or quaternary ammonium compounds, and/or, if desired, the obtained compounds, or N-oxides, are transformed into their salts, and/or, if desired, the quaternary ammonium compounds are transformed into other quaternary compounds, and/or, if desired, the isomeric mixtures obtained are separated into the different isomers.
