N-[(1,3-Benzodioxol-5-yl)methyl]benzenesulfonamide: 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-methoxyphenol moiety, and having a benzenesulfonamide group instead of an aliphatic amide chain. The five-membered ring is in an envelope conformation with the methylene C atom lying 0.221 (6) A degrees 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 fusedring system is 84.65 (4)degrees. In the crystal, molecules aggregate into supramolecular layers in the ac plane through C-H center dot center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
