N-[(1,3-Benzodioxol-5-yl)meth-yl]benzene-sulfonamide: an analogue of capsaicin.
The title compound, C14H13NO4S, an analogue of capsaicin, differs from the latter by having a 1,3-benzodioxole ring rather than a 2-meth-oxy-phenol moiety, and having a benzene-sulfonamide group instead of an aliphatic amide chain. The five-membered ring is in an envelope conformation with the methyl-ene C atom lying 0.221 (6) Å out of the plane formed by the other four atoms. The dihedral angle between the phenyl ring and the mean plane of the 1,3-benzodioxole fused-ring system is 84.65 (4)°. In the crystal, mol-ecules aggregate into supra-molecular layers in the ac plane through C-H⋯O, N-H⋯O and C-H⋯π inter-actions.
