## Abstract A novel chiral stationary phase (CSP) for HPLC was prepared by bonding (__R__)‐1‐phenyl‐2‐(4‐methylphenyl)ethylamine amide derivative of (__S__)‐valine to aminopropyl silica gel through a 2‐amino‐3,5‐dinitro‐1‐carboxamido‐benzene unit. The CSP was used for the separation of some amino a
