1-(4-alkoxyphenyl)-2-phenyl(chlorophenyl)ethanones with paraformaldehyde and substituted piperazines in ethanol furnished 1-(4-alkoxyphenyl)-3-(4-R-piperazin-1-yl)-2-phenyl (chlorophenyl)propan-1-ones. Reaction of the latter with alkyl (aryl) magnesium halides resulted in the formation of tertiary amino alcohols of piperazineseries, which were further converted to dihydrochlorides. The effect of synthesized compounds
