The synthesis of a novel 2′,3′‐dihydrospiro(benzofuran‐2(3 H ),4′(1′ H )isoquinoline] ring system ( IV ) by a nucleophilic aromatic fluoride displacement‐cyclization is described. Preparation of various derivatives of IV as well as the precursor 4‐(2‐fluorobenzyl)‐1,2,3,4‐tetrahydro‐4‐isoquinolinols is also described.
