7-Bromo-2-methyl-1-(phenyl-sulfon-yl)naphtho[2,1-b]furan.

The title compound, C(19)H(13)BrO(3)S, was prepared by the oxidation of 7-bromo-2-methyl-1-(phenyl-sulfan-yl)naph-tho[2,1-b]furan with 3-chloro-peroxy-benzoic acid. The phenyl ring makes a dihedral angle of 80.4 (2)° with the plane of the naphthofuran fragment. The crystal structure is stabilized by aromatic π-π stacking inter-actions between the brominated benzene ring and the central benzene ring of the naphthofuran system of neighbouring mol-ecules; the centroid-centroid distances within the stack are 3.889 (3) and 3.981 (3) Å. In addition, the stacked mol-ecules exhibit C-H⋯π, inter- and intra-molecular C-H⋯O inter-actions.
