Synthesis of 1'-methyl-3-phenylspiro[isobenzofuran-1(3H),4'-piperidine] (7a, HP 365) and the demethyl analogue 9a (HP 505) was prompted by recognition of an aminoalkyl(aryl)isobenzofuran moiety common to the antidepressants talopram (Lu 3-010) and trans-10,11-dihydro-5,10-epoxy-5-[3-(methylamino)propyl]-5H-dibenzo[a,d]cyclohepten-11-ol (MK-940). Convenient laboratory synthesis of 7a was provided by
