Title:
PROCESS FOR MAKING CHIRAL 1,4-DISUBSTITUTED PIPERAZINES
Document Type and Number:
WIPO Patent Application WO2003078420
Kind Code:
A3
Abstract:
A process for a stereoselective preparation of novel chiral nitrogen mustard derivatives useful in synthesizing optically active 1,4-disubstituted piperazines of formula (I) 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.
