Process for preparing piperazine derivatives |
| abstract |
A process for preparing a piperazine derivative represented by the formula (V):comprising reacting 1-methyl-3-phenylpiperazine with 2-chloro-3-cyanopyridine in an aprotic polar organic solvent in the presence of a base and an alkali metal halide. The piperazine derivative and its oxalate are compounds useful as preparation intermediates of mirtazapine. |
