Abstract: In the molecule of the title compound, C₂₄H₂₁FN₂O₂S, the fused six-membered ring has a half-chair conformation, with a pseudo-twofold axis passing through the mid-points of the bridgehead C-C bond and the opposite C-C bond. The dihedral angles between the planar thiophene (B), fluorophenyl (C) and methoxyphenyl (D) rings are B/C = 13.65 (3)°, B/D = 9.72 (2)° and C/D = 23.34 (3)°. In the crystal structure, intermolecular C-HO hydrogen bonds link the molecules into centrosymmetric dimers; these may be effective in the stabilization of the structure.
