A new method for the synthesis of novel C-substituted piperazine derivatives bearing aryl substituents on 2,6-C positions has been developed by one-pot three-component sequential reaction of α-bromoarylethanones with ethanolamine in the presence of formic acid. The structure of the novel compounds was established by nuclear magnetic resonance (NMR), mass spectrometry (MS), and elemental analysis. In
