Introduction of chlorine at the 7-position enhances ligand affinity at DS BzR while chlorine at the 8-position decreases affinity (IC50: 11f, 9.3 nM; 11h, 2.4 nM; 11i, 37.8 nM). In contrast, chlorine substitution at the 7- as well as the 8-position increases affinity at DI BzR (Ki: 11f, 112 nM; 11h, 20.2 nM; 11i, 10.9 nM). Compound 11 is among the few described high affinity DI-site ligands with a selectivity
