The asymmetric unit of the title compound, C(24)H(21)FN(2)O(5)S, consists of two crystallographically independent mol-ecules. In each mol-ecule, the central dihydro-pyrimidine ring is significantly puckered and adopts a conformation which is best described as an inter-mediate between a boat and a screw boat. The least-squares planes of the dihydro-pyrimidine rings are almost coplanar with the fluoro-substituted benzene rings, making dihedral angles of 9.04 (7) and 6.68 (7)°, and almost perpendicular to the meth-oxy-substituted benzene rings with dihedral angles of 89.23 (7) and 88.30 (7)°. In the mol-ecular structure, S(6) ring motifs are formed by C-H⋯O and C-H⋯S hydrogen bonds. In the crystal, mol-ecules are linked into a three-dimensional network by inter-molecular C-H⋯O and C-H⋯F hydrogen bonds. The crystal structure is further stabilized by a C-H⋯π inter-action.
