Para‐substituted aromatic ethers with benzophenone or related structural elements and a 3‐(1H‐imidazol‐4‐yl)propyloxy moiety were prepared by Mitsunobu‐type ether synthesis or SNAr reaction. Most of the title compounds possess high antagonist potency in histamine H3‐receptor assays in vitro as well as in vivo in mouse CNS following oral administration. After defining 4‐(3‐(1H‐imidazol‐4‐yl)propyloxy)phenyl
