Abstract (en)
[origin: WO2005073207A1] Provided are a process for preparing optically active cetirizine or its salt from racemic cetirizine or its salt using glutamate of 2-[2-[4-[(4-chlorphenyl)phenylmethyl]-1-piperazinyl] ethoxy]acetic ester and the glutamate of 2-[2-[4-[(4-chlorophenyl)phenylmethyl]-1-piperazinyl] ethoxy]acetic ester useful as an intermediate for the preparation of the optically active cetirizine or its salt.
