A process for a stereoselective preparation of novel chiral nitrogen mustard derivatives useful in synthesizing optically active 1,4-disubstituted piperazines of formula:
1
wherein R, Ar, and Q are defined as set forth herein, and intermediate compounds therefor. The 1,4-disubstituted piperazines act as 5HT1A receptor binding agents useful in the treatment of Central Nervous System (CNS) disorders.

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.
