Process for synthesizing N-aryl piperazines with chiral N-1-benzoyl(2-pyridyl)amino-2-propane substitution

摘要

A process for formation of N-aryl piperazines with chiral N-1-benzoyl(2-pyridyl)amino-2-propane side-chains having the structure shown in formula below, and for making intermediate compounds therefor. ;In this process, chirality is introduced at the piperazine ring formation step and 2-aminopyridyl substitution is incorporated via displacement. The resulting N,N disubstituted piperazines act on the central nervous system at 5HT receptors.
