ABSTRACT:
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.
